I don't think the pump is 100% the problem. I have to fill up with race gas or AV gas to check. The problem is in the heat of AZ this pump gasoline has a much lower evaporation rate. It is literally boiling away in my engine compartment. When the outside temp is above 90 degrees my car is undriveable. So my car has been sitting since April.
Looks like good work to me Chief but that sure is odd about the pump gas above 90, and I'm dealing with 100 degrees temps every summer here. Is there any chance the set up could be sucking in air between the pump and the tank?
