Here it is. I have a1986 f350 with a 6.9 diesel and I want to eliminate any air intrusion in my fuel injector system by putting an electronic fuel pump in. I have a Delphi CFE0539 12v pump and want to know if it is sufficient for the purpose. It has a max psi of 8 psi, I think it’s range is 4-8 psi. Do I need a pre filter strainer, any other special components etc? If anyone knows anything about this type of project it sure would be helpful. Thanks for letting me on the forum.
