Rebuilt my pump on the kitchen table before a week-long trip and the kit had every little part I needed, right down to the spare jet and the brass fittings. It's not light, but for a stove I plan to keep running for years that's a trade I'll take.

Took this on a two-week trip and the spare brass parts and rebuild bits meant I never had to worry about the pump failing mid-trip. Everything fits in the little kit so it lives in my pack permanently now.

The kit has everything I need to rebuild the pump on my XGK before a long trip, and the spare O-rings and seals alone justify it. Only gripe is the case is a bit bulky for what's inside, but that's minor.
