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 4 out of 5 by from Proper use of the MSR Pump I love reading the complaints, and not to be disparaging, sometimes I find them humorous. Whenever I do read about one of the MSR pumps failing, it's easy to read between the lines and see in all probability what went wrong. To avoid field problems with these sorts of pumps, simple steps must be taken to ensure their reliability. Follow these steps, and you will find your outdoor experience to be always enjoyable. First and foremost, lubricate the pump body frequently by coating with either Vaseline, mineral oil or even wd40. Since fuels have corrosive characteristics, They will leach the resin (over a short period of time) out of the co polymer compound causing embrittlement and slight warping of the body itself. You need not worry about introducing effluent into the fuel source since the ppm (parts per million) is so insignificant as to be not worth worrying about. Next understand that any rubber o ring used in the construct of the pump requires changing annually. Once more the reason is corrosion and degradation of the o - ring compound. Replacing annually will eliminate the leakage problem. Next MSR instruction(s) performs a disservice to the instruction reader: When the pump is not in use, Release the compressed air in the fuel canister since the back pressure serves to destroy over time the pump. Especially when the canister and pump are subjected to elevation changes. Going up into the mountains Once you have released the air pressure, open the valve to allow the trapped fuel within the chamber of the pump to flow back into the canister. This is simply done by holding the pump upwards above the fuel line within the canister. The serves to deny the interior of the chamber corrosive liquid. NEXT do not leave the pump inserted into the canister when not in use. The weekend is okay, long term is assured destruction of pump and the o rings. Lastly a fuel pump, a bicycle pump does not make. If you haul off and pump furiously on the little darling, it's going to break real fast. Lastly, coat the threads of the pump with a heavy coat of vaselline. Do not over tighten the threads. This will ensure a reliable and long term experience with the Ump. Let's examine if what I say is reality. I own a 25 year old MSR Firefly stove which is the fore runner of the current dragonfly. The pump still works fine and is reliable. I own an MSR Dragonfly, the pump is at least six years old and is reliable. In life, you reap what you sew. Regardless, even if the pump fails, simply get another. There isn't another stove system around that is as good as either the Dragonfly or the XGK EX. That's the bottom line. And what's so humorous about the complaints? All fail to recognize self failure and place the blame on the device and not the owner of the device. Who's running the Circus???

Rated 1 out of 5 by from What happened to RESEARCH? On first trip and third use the valve would no longer open. Suspect tread failure without any excess force used rendering the pump unusable. Luckily last trip day, but could easily have spoiled a good trip.

Rated 4 out of 5 by from MSR pump I have owned three of these to go with the Whisper Lite stove over the last 26 years of backpacking in the Eastern US and they have been very reliable during trips. The pump cup and o-ring seals tend to dry out in between trips, sometimes years, and do need oil and maintenance and parts replacement. The latest model, bought yesterday, has a cap on the fuel line that looks like it would block fuel uptake and I find no picture or mention of this in the instruction-maintenance sheet. So I will have to call for information that should have been included.

Rated 5 out of 5 by from Better than the original I bought this to replace an old whisper lite pump that I broke. This one is more solid and will probably last longer than the original that lasted about 15 years

Rated 5 out of 5 by from Works when I don't I've had these pumps for 30 plus years. MSR keeps them updated for a small fee if any. They treat me well. They are my supply chain in recreation.

Rated 5 out of 5 by from Works great My old pump finally gave out. Got this new one as a replacement and it works better.

Rated 5 out of 5 by from MSR Fuel pumps rock! I have had my MSR DragonFly stove for 15 years. The original pump lasted about 12. I never had a problem with it, but the plastic housing did finally break after a few hundred uses. I ordered the latest pump and it is working beautifully. MSR also threw in a new aluminum windscreen, which I wasn't expecting. The new pump works great, and I've never had a bad experience.
