So I installed a new AEM 320 lph pump a couple of weeks ago and put on a new AC delco fuel filter. The pump put out an extra 5 psi over my old XP plus. So I turned it down, then one day my car started to fart and sputter when I started it. I looked ant the fuel pressure was down to 30 psi, so I turned it back up to 42psi and it ran great. Today I took it to breakfast and when I went to leave the fuel pressure was only 20 psi, then I pulled the feedback port out of the regulator. I got the car towed home and put on a new regulator. There is fuel reaching the rail but the pressure is 0. I can hear the pump running but no pressure. I'm wondering if I lost the pump sock, collapsed a fuel filter or possibly lost the hose between the pump and hanger?
Any ideas? Or do you think the pump could be toast?
