RE: Jett Boubbless tank
Davin is, as usual right on. Its always best to follow the insrtuctions, but yes, you can get away with the electric pump. You still have to pull the existing air out of the tank, or pressure the air out from the other line. Lots of ways to skin the cat in a emergency including sucking it out with your mouth as a last resort. But, why not just do it right to start from. When you have 60 seconds on the clock to get ready, one will do some strange things.
