In 1801, Eli Whitney started producing firearms with interchangeable and replaceable parts. In modern times, MSR produces stoves with interchangeable and replaceable parts, utilize this feature. Parts will go bad (eventually). Replacing a pump with a bad seal or cracked component for $35 is a steal in my opinion. I make sure to have a replacement in my gear stash for those "oh sh!t" moments that are unfortunately inevitable in the lifetime of any backcountry explorer.
My MSR Whisperlite International is not pressurizing the fuel bottle. No air is passing through the pump.
We did overfill it with out realizing and pumped it 20 or 30 times and when no fuel came out we realized we had accidentally let it be overfilled at the petrol station. So we emptied some out and tried again and have had no luck getting it going.
Any help with this would be greatly appreciated, as we are currently in Morocco and plan on using it for the next month.
one of the reviews of the fuel pump states that a new wind screen is included, but I don't see that in the product description. Also, does the original MSR Whisperlite come with the wind screen package?(screen and bottom reflector) I don't see it in the picture.
Yes the "MSR Whisperlite" come with the wind screen package (screen and bottom reflector). it is a great pice of art...use it for years (:
this fuel pump also works with primus fuel bottles ?
Yes...don't tell them I say it (;
I've been using the MSR Whisperlite primarily to melt snow for the past 6 years. In that time I replaced the pump O-rings with the maintenance kit once - but I'm not sure it was necessary. However, after at least 60-80 mountaineering trips the pump starting leaking fuel on a pre-trip check. It turns out the plastic body cracked at the threads underneath the brass cap where the control valve is installed. If I had to guess, this could have resulted from over tightening the brass cap, hitting the control valve on something really hard, or from using it as the leverage spot to unscrew the pump from the bottle about a gillion times. Who cares - gear doesn't last forever. I can't believe how much use I got out of mine before it died. Plus, it has always been an excellent (liquid gas) stove. So, moral of the story - good pump, great stove, check your gear before you go - especially if you abuse it like me.
Ill preface this review with my cut and paste statement that I work as a backcountry backpacking guide in Yosemite National Park. Nearly all of the products I take the time to review have seen at least a half a season, if not more, of use... and Im committed to not bothering to write a review until I feel like Ive really gotten to know a product. I never thought Id bother to write reviews, but Ive recently decided that since Ive spent so much time over these last many years reading reviews, and finding a tremendous amount of value in articulate and well-informed opinions, that I wanted to give back to the community. So, with that being said, here we go...
Once, and just once last summer, I was on a trip where we had one of the old pumps, before they were redesigned. It threw up its inner workings, along with some fuel, all over my feet and hands. This happened far too early in the morning for me to understand what had happened until about 30 seconds later. However, this particular pump is one of about ten of these pumps that we use. I've never had a problem with any of the others. And, once we returned home, we ultimately verified that it was one of the older pumps, and that it had decided to sneak out on one of our trips to commit its final act of hari kari during an attempted breakfast.
Aside from this older, less reliable anomaly... these pumps are bombproof. We beat the hell out of them every morning and evening all summer long, and they faithfully tolerate our use and abuse. Occasionally we will have to clean one a bit, usually because it has developed a thick patina of granite flour, and further pumping begins to strip the pump shaft of its beautiful red plastic due to abrasion.
These really are the unsung heroes of our trips. We never praise them. We just beat them up, and they happily help us cook our pancakes, bacon, breakfast burritos, spaghetti, and chicken fettuccine. Its about time they get a few strokes... no pun intended.
My pump valve is stuck - won't move in either direction. Help? Thanks.
Get a maintenance kit, disassemble the pump, replace the o-ring and lube it all up. You might have some sort of crud in there, but it sounds like simple deferred maintenance is the likely culprit.
Follow this link. When you get to the page, right next to the product description it says "MSR pump maintenance"- click on it and it will give you a full video tutorial on how to do it.
I have an old whisperlite that I purchased from Saint Michael's College wilderness program when they were upgrading equipment. It survived years of abuse from college kids no problem. Then I let my friend borrow it, bad choice. He returned it with a shattered fuel pump. Bought one of these guys and she works like new, even better than it did before.
I would agree that the Whisperlite Int. is possibly the best stove ever made. I have had mine since 1997. I have never had a problem with my stove. It has never clogged on me, and if one doesn't over pressurize their fuel tank, this stove can sort of simmer.
However, this is my third pump for said stove. My original pump lasted many years before it developed two cracks in the body, near the control valve. So I bought the "new" design as a replacement. I was able to use it a few times, like twice, before the o-ring on the control valve went bad. So I bought a $30 maintenance kit to replace all the o-rings, etc. While putting the pump back together, I overtightened the control valve, and sheared off the plastic fitting. My Bad. So, this is my third pump in 14 years.
Advice: Be gentle when maintaining the pump, they are not 'bombproof.'
i have a ten year old dragonfly, very pleased with it but now in need of a new pump as it is leaking a bit..will the new dragonfly pump fit my stove? somebody thought it might not.. cheers
Have no fear, the new MSR fuel pump will work even better on your older stove, especially simmering. Select the all red one. It is Dragonfly specific. You should also consider purchasing the maintenance kit @ the same time if you don't already have one. It contains all the necessary parts you'll need over time to keep your stove running to optimum performance.
Select the Dragonfly specific maintenance kit:
I brought my MSR whiperlite intl. at 2007.
The pump is exactly like the above one.
After a few trips, the gas started to leak from the valve controller.
Fortunately i used to test all my gear before the trip, so that i won't have any trouble during the trip.
i have sent it to the local dealer and they repaired the pump for me.
It works fine.
But now, the same problem happen again.
i was so confused and really disappointed wif this so called new design pump.
Does any one have some suggestions?
I just took mine apart again for general maintenance & to better see what problems you might be having.
1. Using a 7/16 open-end wrench, carefully unscrew the brass valve housing.
2. Unscrew the needle valve assembly.
3. Inspect & lubricate the small red o-ring. Use MSR Pump Cup Oil to lubricate or if you don't have that, use a small amount of petroleum jelly & wipe away any excess.
4. I couldn't find that specific o-ring in either maintenance kit so if it does need to be replaced, contact Cascade Designs @ 1-800-531-9531, explain your situation precisely, & I'm sure they will send you the part you need.
5. Carefully reassemble the valve.
6. Also replace the fuel tube o-ring on the opposite side of the pump @ the same time. This o-ring is included in both maintenance kits & is the most prone to needing replacement since it does have direct contact with fuel.
I hope this helps.
Thx Jeff, you are helpful.
yes i can't find that specific o ring too.
I think I will try to apply some oil on the o ring first
and if the gas continue to leak I will contact cascade designs or just buy a new one.
I've used a WL for years. I think the problem you're referring to is a flaw in this new design: The valve control is now that long affair that folds down, instead of the old thumbscrew. As a result, when it's folded, it acts as a lever arm and normal bumping around in a pack can cause the valve to open slightly. Bad news! Especially because there is no fix available. The best you can do is be sure to close it tightly, and then pack it so that the valve is reasonably protected.
Everything else about the new design is good. This control arm thing, however, was a mistake.
I have and old MSR Firefly stove I bought in 1984. Will the new Standard or Dragonfly pump assembly work on the Firefly? The old pump melted when it caught on fire due to a fuel leak.
If you send MSR what's left of your old yellow pump that came with the Firefly, they'll give you a discount on a new one. Call them to set up the details- 800-531-9531
I'm not a betting person but I'd bet most "Gear Guru's" don't remember the MSR Firefly.
A little history on the firefly. It was first introduced in 1983 with a clear plastic fuel tube which was quickly recalled for obvious reasons. The replacement was the black mesh fuel line which was the same one used on the original WhisperLite. Shortly thereafter, the Firefly was no longer produced. The one's that are still being used are accident's waiting to happen due to fuel leaks similar to what happened to yours. Three years ago I spoke to to MSR regarding this exact subject. They informed the Firefly should not be retrofitted/updated for any reason whatsoever & there was also an upgrade credit available. Like I previously mentioned, this was three years ago & I don't know if this is still an option. It is best to call them directly & explain your situation. The folks @ Cascade Designs are very fair & understanding & I'm sure they will will be happy to work with you.
Please give us an update on your situation. Good luck.
Phil, Great picture. Remember the little clip on the fuel pump that propped the bottle up so it would draw fuel from the bottom? I sold mine on eBay in 2007 as a COLLECTOR'S ITEM ONLY. NOT INTENDED TO BE USED AS A WORKING STOVE!!!
I gotta give Monte Dodge credit for the photo, but I figured you would get a kick out of it...and laughed myself when I thought back on it. The perfect stove for people who like to play with fire. I'm surprised a stove aficionado like you parted with it. I'm wondering if Tim only melted the pump recently, or if he was going through the attic and decided to see if he could salvage that old stove that he flamed out during the first week he owned it? External frame backpacks with huge sooty aluminum pots hanging from them, Sierra cups, wool mid layers, legally hanging food in bear country...and still managing to survive for all these years.
I used the new pump on a 5 day backpack trip. It worked awesome and i think that i used less fuel? at any rate i returned home with more fuel than i usually do. It is so nice to have gear that is easy to use and efficient. We had a gal that had never backpacked before and it was great to be able to show her how easy stoves are to use...a big confidence builder for sure! thanks again for the support you show for extreme athletes and run of the mill 50 year olds like me!!!
Write your question here...I have a dragonfly stove that is approx 10 years old and there is a crack in the plastic pump portion. It still works, but am thinking about replacing it. Will the new pump work on that old of a stove?
Absolutely! I would highly encourage purchasing the DragonFly specific pump especially if you see any indications of cracks or leaking. Because you are dealing with fire and volatile fuel, replacing the pump will be in your best interest. The new pump is much more durable and includes a new windscreen as well. This is a very wise purchase indeed:)!
I would highly encourage you to contact Cascade Designs Customer Service Department first @ 1-800-531-9531 & explain your situation before purchasing a new pump. Under normal usage, your pump should not have cracked. I have an old black & gray pump from 1988 for my original WhisperLite that still works fine & isn't cracked. The people @ Cascade Designs are very understandable & easy to work with.
I have the same issue - the stove held up for a number of years but I think it cracked during a move. It is now leaking fuel and this is a dangerous situation.
The pump listed looks identical and I plan to purchase one for my dragonfly stove.
Best of luck with your stove
Will the Dragonfly fuel pump work with the Whisperlite International stove?
No it won't. The reason is the pump the Whisperlite International uses doesn't have an emergency shutoff valve due to the extra flame adjustment valve located on the DragonFly stove. Because of the DragonFly's simmering capability, MSR felt it necessary to design an emergency shut-off valve into the DragonFly's pump. This is why there are two pumps (Standard Pump which will work on all MSR's liquid fuel stoves (Whisperlite, Whisperlite International, Simmerlite, and XGK EX) and the DragonFly Pump).
If you try to use a standard pump with a DragonFly, you will find the fuel line will not fit into the hole required by the DragonFly's fuel line. Visa versa, the Whisperlite International (and all other MSR liquid fuel stoves) won't work with the DragonFly's pump because of the too-large hole which only fits the DragonFly's fuel line.
A while back when I was a fair bit younger, still in high school, I went hiking with with my whisperlite stove. The fuel bottle was full and I over pressurized it. It started leaking. That leakage caught alight. It blew up. The whole thing was torched and the plastic pump completely melted. The stove was also adequately bathed in flame. I've been using a Trangia for the last couple of years, but would like to go back to using the whisperlite.
My question is. Do you think the stove would still be safe to use, if a replacement pump and bottle were acquired?
If I were you, I'd pop for a new white gas stove. The Whisperlite is still an excellent option, but, like phil said, once you purchase the repair kit and a new pump, you've basically spend as much as you would on a new stove of the same type. Purchasing a canister stove is always an option too, but I like having a white gas one as a primary; over time, it will cost you a lot less than a canister stove of properly maintained (taking the cost of repeated canister purchases into account vs. filling your white gas bottle).
Nostalgia isn't worth the hassle...get a Dragonfly, they rock.
The pump works as expected.
The only concern I have is that the valve handle feels a little flimsy. Like it won't last too long.
The pump has been great for me. I have used it in bitter cold and hot weather. No problems. I do perform periodic preventative maintenance and corrective servcie. (PMCS).
I bought a whisperlite about a year ago and I think it has an old pump, it doesn't look like the one in the picture, it has a small aluminum dial for flow control not the big red plastic knob, and it has two plastic white tubes and doesn't have the right angle like the one in the pic. Am I right, do I have an old pump?? and if so is there any way I can get msr to replace it with a new one??
Even if it is an old one is there any reason for me to upgrade the one I've got (works fine by the way)?? I only cook simple meals that require boiling water, oatmeal, tea, pasta side dishes etc.
I got my whisperlite int'l 2 years ago and it has this pump in it. Perhaps your stove is older? Either way, unless there is something wrong with it, I don't think you need to replace. I don't think MSR will do it for you either, especially if the one you have now works. Look at the Q & A below this for the advantages of the new pump.
There are some compelling reasons why you would want to buy the new pump, but it isn't necessary. If the old pump is working then there's really no need to replace it. I would give the old pump a thorough inspection most especially looking at the O-rings (the big O-ring where the pump screws into the fuel bottle is the most critical). If you see any cracking of the rubber or any cracks on the pump itself I would replace it. This is not a warranty issue since it's most likely due to normal use. If you suspect it is a warranty issue, call Cascade Designs at (800) 505-9500 and they will issue you a Return Authorization Number. You will need to send it back and, after they inspect it, determine that it isn't a warranty issue then they will repair it for a reasonable fee. They can help you over the phone if you have specific questions...
The new pump will allow you to simmer better (not like a canister stove, but gives you one full rotation of adjustment vs. the old pump that gives you no rotation adjustment). It's also much more durable, won't spray fuel when you release the pressure after unscrewing it, and is much easier to maintain (no leather plunger). It also comes with a new windscreen which is a $10 value.
My opinion is the $35 for the new pump is money well spent and will upgrade your stove to the latest version of the Whisperlite. The most resent updates to the Whisperlite have to do entirely with the pump, not the stove.
I have a MSR Whsiperlite, with the original fuel pump, but the plastic part, I think is called the "ears", that holds the actual pump broke. Can I still use it since all it does is hold it in place or will fuel leak out?
I would recommend getting a new pump. If anything is broken on the original pump it should be considered unserviceable and discarded. The reason is you are dealing with a very volatile fuel (white gas) and fire. If any of the fuel leaks out or the pump doesn't seal properly to the stove, you risk having the whole thing light up like a Christmas tree. I've seen it and it's not pretty. There are some neat advantages in getting the new pump anyway. For one, it's more durable. Two, it gives you better simmering capability, and three, it comes with a brand new windscreen. It's well worth the money and will update your Whisperlite significantly. It is one of the few upgrades that is strongly recommended. The Standard Pump is what you want...
