    Quick Fuel ss-650 in a 331 needs a fuel pump

    Been away from this forum for about 8 months dueo to a house move and lots of projects there.

    Currently its got the mechanical pump, we are thinking that the mechanicl pump has a pinhole or something like that, so I want an electric fuel pump may with a regulator, not sure about that. The QF pumps seem to like around 6 1/2 pounds of pressure. Will leave the mechaiical in there for now and put a block off plate in the future.

    Looking for recommendations, this is a non return fuel system cause its a carb.

    Thanks !

    Hey Bob, glad you're getting back to it. Holley makes an electric inline pump that is preset at 7psi, no regulator needed. If you need more flow (I dont know the flow requirements of a 331 at full tilt), you may need a 14 psi pump with a regulator.

    Heres a link to a doc with part numbers and install directions.
