Fuel Pressure for 06 5.4L
Did a search and came up empty handed. Anyone know what the fuel pump discharge pressure prior to the filter is supposed to be as well as the rail pressure? My pump sounds kind of weak, even after the filter change but I don't want to drop $400 for no reason. If I had a tuner I could see the rail pressure but i'll probably just hook a gauge prior to the filter if anyone know what it's supposed to be.
