I don't think it's pressure. I think the fuel pressure gauge is going wild because there's air in the line.




My Fuel presure goes to 0 when it sucks air. It is a electric pump.

but how could a mechanical fuel pump possibly be getting that much pressure built up?




A electric pump may have a 1/16 of a horsepower driving it. Why is it that you don't think a engine that is making 300 horse cannot drive the fuel presure of a mechanical pump to over 7 psi?


Allen Here's a novel idea, let's not throw a bunch of parts at the car hoping it will fix the problem and instead spend a little time diagnosing it first. Life was a little easier when I was just a wrench.
