How Much Fuel Pressure is Required to keep a 7.4 Liter Fuel injected Motor Running Great, I fear My Fuel Pump is Failing. Any advice would be Appreciated. Thanks in advance. I was Driving Howe and a Mile away It acted as if it was out of Gas. Called Neighbor to pull it Home for Me.
55 to 61 psi key-on, engine not started. I Googled that and got an answer in about 20 seconds.
If the pump’s never been replaced, it is very likely the 21 year old pump.
