wolfe10 Report post Posted June 29, 2014 Here is what he posted as the fix, and we are just ASSUMING that the hose he replaced/had a leak in was between lift pump and HEUI pump. You are absolutely correct-- a leak before the lift pump would suck air in, a leak after the lift pump would be pressurized and leak fuel out: "It has been Fixed. Problem was with the high pressure fuel pump, and a pin hole in the incoming fuel line. Replaced pump, high and low speed sensors, some o Rings and a fuel line... ALL IS GOOD NOW!!!!!!!!!!!!!!!!!!!!!!!!!!!" Share this post Link to post Share on other sites
