So I had modified my fuel pump assembly when I installed my Vortech & Walbro...drilled the fuel pressure regulator out, discarded the yellow nozzle, and drilled holes into the housing. Ever since then I had problems starting the car only after filling up on gas. I thought it was the injectors or some combination of things, but I removed the Vortech and am back to stock injectors now. The problem still persists, so that leads me to believe the fuel pump assembly is to blame for the starting issue.

Does anyone have a solution to this or have a spare fuel pump assembly available? I still have my OEM fuel pump, so I'll just need the assembly.

 

the problem is that you discarded the yellow nozzle. thats a critical piece and is only supposed to be drilled out a little, never discarded.

good luck finding one though. they are $$$$ from the dealer.

 

Yeah I just followed the turbonetics manual which said to discard it. Lesson learned. What exactly does that piece do?
