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.
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.
Works fine, keep attached to stove in pack
I saw all the complaints, so decided to write a review since the new pump has worked fine for me. I keep it in the fuel canister and attached to my Simmerlight stove for the whole backpacking trip, 2-6 days, in cold (13k feet, below freezing) and hot/dry Zion NP in July (100+ degrees) environments and it has never leaked, and nothing has broken. I did just clean the inside of the pump housing and lubricate the rubber pump cup. You do have to have the pump shaft in the correct position (~1/2 way down, so the tapered section has just disappeared) in order to twist and remove the pump shaft, otherwise it will not twist and you could break it or the collar.
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.
Great Stove, Pump is Achilles Heal
The MSR WhisperLite used to be my go-to stove for cold weather camping. I love the stove: light, compact, easily fires-up. Unfortunately, the pump is an Achilles heel and it is not inexpensive to replace. I've owned two over the last 20-years. Both have exhibited the exact same failure mode - the pump housing cracks at the shutoff valve. I understand worn seals, but the housing should hang in there. The second failed after a fraction of the uses the first one did. If you've fuel in the bottle it leaks. I've gotten around the problem with Gorilla tape and a spare bottle to keep the fuel in. But what an inconvenience. All I have to say is: Caveat Emptor!
MSR Fuel Pump
I've only had the pump for two years. It broke halfway through a high Sierra backpack. I was using the pump to do what it is intended to do - add air pressure inside the fuel tank. I pushed the pump in. Then it would not retract! I finally worked it free. Pumped again. Now it "stuck" for good. The pump handle won't retract. By the time I finished my hike, the stove barely generated a flame due to lack of air pressure inside the fuel tank. The stove is great. The fuel pump is the issue. I've backpacked for five decades. This isn't "operator error". The pump is the issue.
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.
Great, but not for some older stoves.
The pump itself works great on newer stoves such as my XGK EX, however I purchased a replacement for my older WhisperLite and this is where I feel my observation should be noted. The original WhisperLite pump had a brass wheel for the control knob. The newer versions have a folding knob. Although easier to use in cases such as wearing gloves, the newer design comes into contact with the locking bail on the fuel line. Turning the fuel on is a counterclockwise motion and turning it off is, of course, clockwise. This has caused some concern since turning the fuel off comes into contact with the bail and hinders the operation should one need to cut the fuel supply in an emergency. Unlocking the fuel line from the pump would cause a pressurized fuel spray, thus causing a flare up. In conclusion, this is a great pump, but beware of its use on legacy designs.
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.
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!
