Getting crews ready to head out I've had 2 of my 6 MSR fuel pumps for Dragonfly stoves come into my office "broken". After disassembling I realized both of them had the plastic threading for the fuel flow plunger assembly stripped, giving the plunger no way to move inward or outward in the housing.
I've got a call in to MSR to ask about the problem, but was wondering if you folks had some ideas. The damage itself can easily be attributed to user error; rotating the valve beyond the end of the threading, but I've seen this same issue crop up enough times to consider it a design flaw.
I might try popping one on my drill press and see if I can replace the plastic threading with a threaded tube of some sort of metal. Not sure about how much room I have to work in there or what adhesives to use, but it's not like I'm going to break it more.
Is it possible to rig an Optimus or Primus pump into the MSR stoves? Any other ideas on solutions? Hoping to avoid having to completely change out our kits as things break, but replacing the pumps with any regularity gets expensive real quick.

Why not use primus stoves? Had mine for 10 years and nothing has broken.

griegs - can't quite picture what's failed on your msr pump.
(and I'm looking at my msr pump right now)
what you're saying sounds real bad though. Do you mean the threads that hold said pump in the fuel bottle itself?
edit: ok. Think you said plunger when you meant to say
Pump Control Valve. Big trouble.
post an image of the shizzled piece?

Broke the tabs that hold the plunger in with in a few time of use, but still works. it is annoying though.

Pictures of the damage. You can see the wear and what remains of the threading pretty clearly. When I cut the cross section some of the threads were detached in places.
Hope that makes more sense.
