Anyone use the new MSR arctic fuel pump? In the past I've had some issues with o rings leaking and pump cups not always sealing well at super low temps and wondering if anyone has any experience with this new pump?
Interesting. I wonder if it is just updated rings and pump cup? I've got several pumps and would love if they came out with a service kit that could be used to upgrade a standard pump. If I was gearing up for an expedition I might give them a call.
