One of my 7.3 idi is the marinized version done by star Pwer (correct spelling). I put in a new electric fuel pump in preparation of this years boating season. In my truck I run the same electric fuel pump set up with no problems. It will give me about 8psi. In the boat the pump is much closer to the engine and it does not have to push the fuel up hill so I am getting around 12 psi. I am considering a fuel pump regulator to bring this down, but besides my fear could I be doing the pump harm with that much fuel pressure. She started better than ever before with my pre season shake down starts, but this concern me. Been a fan of this forum for a few years now, but the first time asking the question.
Am I hurting the injection pump by putting around 12 psi to it?
