My 302 Merc has an electric fuel pump and a mechanical fuel pump. When I turn the key the electic fuel pump comes on and stays on. The fuel then goes through a filter, then the water sep, then the mechanical fuel pump then to the carb. In between the mech fuel pump and the carb I have a fuel pressure indicator gage. It will constantly read between 8psi and 10psi. My Seloc Manual (Tha'ts right, I said it, Seloc) says the psi should be between 3-6psi and my ford manual(the original service manual for the 302 marine) says the psi should range between 5-7psi. Before I ask my question I want everyone to know that my float settings on my 2bbl holley are correct.
I know that the Mech fuel pump was modified for the marine world at the factory so my problem is this, what is the best way to control the pressure? I was going to buy a fuel regulator but read on iboats that either they suck or they are too expensive so I was thinking about doing this. Placing a on and off valve(I don't know the technical name) after the fuel tank and before the electric pump and controling the pressure buy adjusting the amount of fuel that goes to the electric pump? Either that or a buy a new electric pump all together.
Any thoughts?
