Iíve got this one. I screw it on loosely until I need it, then keep it on once Iíve broken the seal (been using 25oz carts, so get a couple fills out of one).

I also have the OneUp EDC pump and kit. No hose, but really nice pump, and having plugs and tools packed into a single portable device that I always carry makes up for it.
