Just when I thought I had my GT fixed, now it has low fuel pressure I have a 255 LPH In-Tank BBK fuel pump (1 year old, but has less than 5 hours of run time on it). The car is full of gas, pressure goes from 10psi initially and rises to around 22ish. Does the pressure with the 5.0 fuel pumps vary w/ voltage like some pumps I read about in the probst book? Could it be just a bad connection/bad wiring? I have it hooked through a toggle for now; the pump turns on fine, just i'm getting low pressure. The filter was also changed a year ago, but again, only has minimal run-time on it. Sound like I need a new pump?
