Did you use a fuel pressure gauge using the carter? At start up I have 3lbs of pressure after the truck warms up I have maybe 1/2lb of pressure.
Pump is running and not hot. I removed the stock filter just to check same deal??? I have used electric fuel pumps before and they will pump and then stop when the pressure is built up. Is this pump suppose to continuously run it never cuts off? Not familiar with it, that is why am asking? Any info would be helpful.
