Stuppid question ,but why doesnt the fuel pump being immersed in fuel just short out between the pos. and neg. terminals ? Does gasoline conduct electricity?
fizassist said:Gasoline has a low electrical conductivity, but more importantly, all electrical connections are insulated from the gasoline.

We had a demonstration from the local fire department. The fireman actually put a match out in a cup of gas (he knew what he was doing).
So long as the connections are connected and there is no arcing all should be OK.

As long as the electrical connections are tight (they're usually screws and ring lugs,) you'll be fine. You just don't want any sparking - especially with a low fuel level...

Simple, No Oxygen=No flame, I learned that while working on aircraft & noticed all the fuel pumps were in the fuel tanks!.

Also, if I put my head lite in the fuel tank and turned it on, what would happen? Thanks for your thoughts.
