Rated 1 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 1 out of 5 by from 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.

Rated 1 out of 5 by from Plunger seal broke first time out Bought this stove yesterday and it cooked supper last night. This morning the plunger seal was no longer in place and will not stay put. Stove seems great but the tank pressurizer assembly is questionable. Will have to see how the company handles this.

Rated 2 out of 5 by from 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.

Rated 2 out of 5 by from 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.

Rated 1 out of 5 by from 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!
