Crazy idea

If I need to run an engine for a while with no fuel tank or pump or whatever, I have a plastic fuel tank, taken from some bratty kid's Honda XR80, that I hang from the hood. The tank even has a little - dare I say - petcock that allows me to turn the gas flow on and off. But plumbing in an electric pump until the mechanical pump can get primed? I van honestly say I would only do that if I were very, very, very lonely.
