fuel pump bleed after shut off fc
I was wondering if it is common for the fuel pump to bleed down after the ignition is off with a weak fuel pump. Injectors are not leaking and fuel regulator tests fine. Fuel pump tests weak and only peaks at 45 pounds with line plugged. I ordered a new pump because pressure was weak. Am I missing anything on other possibilities of a bleed down. Intake is off and no fuel leaks visible very fast bleed down.

Either you have a leak, or the pump is bad. There is a check valve in the pump that if failing will cause pressure to drop fairly rapidly after the pump shuts off. Perhaps the pump is completely clogged with crud.

thanks, it does bleed down rapidly. I am hoping it is the fuel pump. Could not find any other leaks. Got a walbro on order. will see if that does the trick
