MSR Fuel Pump Reviews:

Positive Reviews:

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.

I don't get people's problems with this.

I honestly don't understand people's complaints on here. I have used this pump with the Whisperlite International in all kinds of environments and weather. From the summer heat in the sandy deserts of SE Utah to -10F winters in the the mountains of Wyoming it has been great. Would I like it if there was more metal and less plastic? Yes. But does it do the job it is supposed to do while at the same time being completely field repairable? Yes. Every part on this thing can either be fixed or replaced in the field in a matter of minutes with a little practice. Tightening plastic onto metal threads until it cracks is not a design flaw. That is simple carelessness. You say it can't simmer? I say you don't know how to get the most out of your stove. It can if you are willing to watch it (as it may go out) be turned down to a low setting. You can also bend the windscreen from your stove to allow you to rest a pot/pan several inches above the stove thus lowering the temp even more. You can also let a little pressure out of the fuel bottle and make it easier to get a low flame. Learn how to do your regular maintenance on it before your big trips, have some spare parts just in case, and be creative in getting the most out of your equipment and you will be fine. It's not perfect but I'd take it combined with the Whisperlite International over another stove any day.

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.

Seems up to the job

I received this to replace the pump for my old MSR Whisperlite Int'l which finally broke. I was initially concerned about reviews I found online about this replacement pump not having enough flame control. I have only tried it out on my kitchen counter, but it seemed to have a decent simmer setting while still packing the punch of the traditional flame-thrower rapid boil. I expect it to do well in cold whether. The price certainly beats buying a new stove, and, as expected, it fits all my MSR fuel tanks.
Chuck K. at Eastern Mountain Sports (EMS) on 12/12/2012

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.

New and much improved

The MSR fuel pump is a marked improvement over the old style pump that I'd bought in the early 80's that finally released its sun-bleached soul.
The new style is more compact and has a much improved valve that allows you to simmer. The old style only allowed medium-high and blowtorch mode. By the way, I'm using a Whisperlite International (non-shaker jet, old-school)stove.
Made a good ol' stove even better.
Scott at Campmor on 10/10/2012

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.

New & Improved

This is an improved design on the old standard. The newly designed valve adds flame control especially when simmering. The plastic material is just as substantial as aluminum, used by other manufacturers, only lighter. Good pump seal. Needs occasional lubrication.

*Better for use on stoves with newer fuel line catch arms so the valve control knob can turn unimpeded.

Cheaper to replace half than buy whole

For winter camping, s gasoline-fueled stove works worlds better than propane/butane stoves or any other kind that I've tried. MSR gasoline stoves, such as my Whisperlite International, are the best. Its a two-piece stove - burner and pump. But nothing lasts forever, especially the pump. Fortunately, in MSR sells replacement pumps at about half the price of the whole unit.
Bill the Volcanologist at Eastern Mountain Sports (EMS) on 02/02/2011

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.

Negative Reviews:

Be better in metal

This thing is useless. When I buy a whisperlite, it is probably for its extreme AK-47-like reliability, but then there is the pump. Why? Why is it made out of a plastic that will crack and leak 10 days into a 21 day, 201 mile AT hike? MSR needs to hire actual backpackers to engineer their products. I would not mind if they added a few grams and a bit more money to make this out of aluminum or titanium. The stove, however, is excellent. If every single pump is like mine, you should probably carry one for every five days on the trail, just to be safe. Hopefully I just got a fluke.
Unfortunately, MSR whitegas stoves are all ruined by this horrible pump. If I were you, however, I'd get one of them whisperlite universal stoves. Yes, they are more expensive than the other whisperlites, but at least you can use the same stove on isobutane and whitegas. That way you can get the same whisperlite reliability and you can just use isobutane until the pumps get better.

good stoves but terrible pumps

MSR has always made great lightweight stoves but have made terrible pumps. I have been through three generations of pumps. The first generation came apart on a winter trip scattered fuel everywhere and set the snow on fire. Tabs holding the pump handle broke off. The second generation also breaks tabs but at least it didn't set me on fire. It also simmered well. The third generation (shown here) switched to a rubber cup instead of leather so it siezes in hot desert weather. You have to oil it often. The check valves fail easily. It will not simmer. Nor does it turn off properly leaving the stove burning at a low level. You have to blow it out to be sure. It also has weak plastic threads that strip easy. It no longer has an O ring on the bottle so it will eventually leak in your pack. The second generation pump was the best of a bad lot but this new one is worthless.

I wish MSR made a metal one

This pump worked for a while, but when I was in Philmont with my son, it sprung a leak. It took me a while to find it, but then I noticed a 3mm hole under the hole where you put the tube from the stove in. It frustrates me. The whisperlite will last for many, many years. It is built like a tank! But the pump on the other hand, well, it will break if you don't treat it very delicately. I would only use this for car camping or day hikes, where you aren't relying on your stove to light. The ironic part of all of this is that MSR was started by a group of guys that lost their friend because their stove wouldn't light. If only MSR made a metal version. If you want a stove that has a metal pump, go with a Soto Muka.

poor quality pump

I've owned my whisperlite stove for 15 years and used it on extended cycle touring, backpacking, winter camping, and canoe trips. The stove has proved functional under a variety of conditions and temperatures.

While I've never had a problem with the stove, this pump is another story. I'm on my fourth pump. The last one lasted only a year. These pumps are not very durable and the pump pieces seem to be made with cheaper and cheaper quality plastic pieces with each new pump.

I'm switching out to a cylinder base stove that doesn't require a pump, like the pocket rocket or jet boil. They're lighter and I'm tired of replacing these pumps. They always seem to break at the beginning of a trip.

Great stove, bad-bad-bad (new) pump

I have a whisperlite International for over twenty years and are extremely satisfied with it. Last years the o-rings finally gave in so i ordered a replacement pump as well as a maintenance kit. Replaced the o-rings on the old pump; works as new!!!
On my last 4 day camping trip I brought the new pump to give it a try. On the second day (!) the part that keeps the plunger in place broke. I did not use very much force, and after using a whisperlite for 20+ years, I think I know how to use a pump correctly.... This is extremely disappointing of MSR considering they really make an extremely good product (the stove). This pump is NOT, I repeat, NOT reliable.
Nutellafan at REI on 10/10/2013

great stoves, fragile pumps.....c'mon

Agree with other posters. Great stoves, but the fuel pump.......
Works fine, but definitely plan on buying 2 or 3 with your new stove. It's a little finicky when disassembling for service, and if you don't align tabs exactly right, they break easily. I don't like fragile equipment in the backcountry, but if i want the stove, I have to get used to the idea of a lousy pump until MSR gets their act together. I "recommend to a friend" only because the pump is essential if you have the stove. If I can find another brand that will do the job I'll switch in a heartbeat...

poor pump, but no choice

We use a Whisperlite International for all our backpacking. The stove is great and we have had it for at lest 12 years. I still use the original pump mechanism. But, I want a backup pump. I have tried this twice - the first new pump resulted in a scary jet of flame shooting out the stove that melted part of the aluminum screen. The second works, but leaks at the fuel bottle - no O-ring, just the rubber fitting. I kept this one as a backup, but I just hope the original pump lasts! The stove is great, wish the new pumps were as good.
Blueberry grazer at REI on 10/10/2009

Leaking after minimal use...

Sorry that I'll have to add my vote to those that feel this is cheaply made.
I love the stove, but this would appear to be a very weak link to the system. After two trips of light use the pump assembly has sprung a leak and I need to replace it after testing it out prior to bike tour starting in a couple of days.
I'll replace it since I don't have much time to consider other options but will be making a different choice soon after this trip.

Another Bad Pump Story!

I have had my Whisper Light for 15 years and love it but as everyone has said, "The pump really needs a redesign." My first pump was the best until I cracked the pump housing. The newest pump failed during my first camping trip. I closed the pump too tight and stripped the value screw threads. I couldn't get any fuel to flow. In other words, this pump did not even last one camping trip. I love the Whisper Light so I guess I'll buy another pump. Sigh!
Thomas P Gross at REI on 06/06/2011

Not for the heavy of hand!

Before I could barely get the pump out of the box, the fuel valve (plastic portion) broke off due to overtightening it. Problem was, that it didn't take too much force at all to have it come apart in my hand. I was so thankful that I did not have it out on the trail! that's a scay situation to be perfectly honest.

Neutral Reviews:

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....

Ben at on 06/25/2013

Serves its purpose, but does not last

My MSR WhisperLite stove has lasted over a decade, has been through extremely harsh conditions,and has performed admirably...I've had to replace the pump, however, multiple times. The pump's light weight plastic design is okay as a weight saving measure and it works great brand new, but the pump's issues with long-term durability and constant need for maintenance have always been the WhisperLite's Achilles heel. That being said, I still prefer the WhisperLite to any other stove.
The Spartan at REI on 05/05/2009

Great performance, until it breaks

Great stove, except when I took it apart to clean it and over-tightened the fuel knob and cracked the plastic. Faulty design. I noticed someone else did the same thing. Now I have to buy a new pump after I just purchased the "maintenance kit"; it's almost cheaper to buy a new stove.
