Like I said sorry for another fuel pump question but this seems like a great place to go to get your questions answered correctly. I have a 5.0GIPEFS serial number 4012005198. I was told by a local shop that I needed a new high pressure fuel pump do to low pump pressure 12psi. The first took the pump apart to try and clean it and try to get the boat running again. I wanted to make sure I could by and replace just the pump or do I have to buy the entire fuel pump with both pumps? I had some issues with this local shop and dont think they know what they are talking about so wanted to double check. Thanks again for you time in advance

Thanks for the help installed the new high pressure pump but now after about two minutes I can start hearing a whine from the fuel pump. Wondering if anyone had any thoughts on this. I did have the entire pump off and don't think I connected the two pump wires backwards but if I did would that mater

You can hook them up either way, but they are fused separately.
Whats your fuel pressure now?? High and low pump??
