Gasoline vapor, but not a combustible mixture. Even
when the gauge shows empty, the contacts are still in the fuel. mike hunt Ken Weitzel wrote: > > wrote: > > Perhaps if your degree was in electrical, rather than mechanical, > > engineering you might.

Are you sure? The pick up is under fuel, but is the pump completely under fuel ?
The "contacts" are in the top of the pump, so exposed to tank atmosphere. Being no O2 or not enough to support combustion.........moot point. > wrote in message ... > Gasoline vapor, but not a combustible mixture.

Much more comforting that having the pump outside the tank where all of the ingredients are available. :-) Matt |
