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.
That sucks! Do you use stock fuel lines or did you put some after market lines in? I havent had any problems with gas boiling away from the heat and I usually have anywheres from mid 90 to 100 degress with high humidity here in NC. I do have a vapor return line though. You running a stock engine or built up engine?
