Darn. I've got a combination pump and CO2 inflator, but without going out and looking, I can't remember the name or brand. It's about 8" long, give or take. Basically, the pump is to inflate enough to find a leak and puff up the tube to make installation easier. They claim you can get 80psi from it, and they've probably got some gorilla on the payroll to prove it can be done. It works with both presta and schrader valves. I carry it, and hope I never run out of gas cylinders.
