The new version is poorly built and prone to constant failure requiring field repair.


  • Field stripable


  • Valve is cheaply made
  • Seal fail quickly
  • Pump casing subject to major failure

Had to replace my fuel pump. The new one, now on third one, has had several failures. This last one I considered catastrophic in nature. The ear which holds the plunger in place fractured and broke causing fuel to leak everywhere when I was using the stove.

Wrote MSR with no response. This was pump three. The other two valve casing cracked and seal failure. Have been able to put the three together and get one workable pump, but very discouraging about service.

The stove itself is great when the pump is working. Have rebuilt one using a kit, but one would think MSR would a least write back after a pump casing failure while under pressure during use. They build a great number of great products. The quality seems with their stove line to have dropped.

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 seizes 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.
