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
