Here's what others have to say...

I am trying to remove the plunger to do maintenance on the pump cup but it won't twist to the left at all. I pulled it out to the open here mark, but it simply will not budge. I don't want to force it and cause damage. Any thoughts?

Is your problem solved? Otherwise, would you mind to do a skype video call to do it simultaniously?

I was finally able to remove the pump and stove is working great! Thanks for the response though.

great pump

  • Familiarity: I've put it through the wringer

I bought this replacement pump for my whisperlite. The pump worked great I didn't have any problems with it.

if you have a msr stove you know that they are the bees knees and they last forever and when there done lasting forever all you will need is a new pump. awesome pump it made my wisper lite int work like new after 7 years of hard use.

perfect fit

  • Familiarity: I've used it several times

My old fuel pump broke after I accidentally stepped on it. It worked flawlessly all its life, but I had to replace it.
This pump works just as well and the fit was perfect.

straight forward

pretty simple to use with your MSR stove, for pressurizing we normally give 30 pumps. I haven't had to replace any part yet but I like how if something breaks in the future it's easy to take apart (and put back together)

High quality...

Good pump

This has worked well for me and I have no problems with it, but I havn't used it much so we will see how it holds up.

Give and take....

  • Familiarity: I've used it several times

These new pumps seem to be more safe than the older ones (ie. Less flare ups). However, they do not simmer as well as the old grey pumps with the round metal regulator. These seem to be durable enough, but I just can't seem to get used to them. I recently sent in my Whisperlite for service and they kept my old grey pump and sent me one of these. Not sure how I feel about it yet....

I should add that there was nothing wrong with my old pump....

Replacing Parts > Replacing Stoves

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...

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.

replace the pump cup on the inside of the pump if you dont have a ex pump cup then take some kind of oil and lube it up neosporain works good

one of the reviews of the fuel pump states...

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.

6 Years of Hard Use - Good Enough!

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.

6 Years of Hard Use - Good Enough!

Redesigned, thank God.

I’ll 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 I’m committed to not bothering to write a review until I feel like I’ve really gotten to know a product. I never thought I’d bother to write reviews, but I’ve recently decided that since I’ve 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.

Nice review... I've been thinking about replacing the pump on our 12-year-old Dragonfly... I'm convinced!

See you in July!
