    Fuel system component questions?

    Hi all,

    I'm trying to sort out a pluming diagram for my fuel system.


    I have a Carb’d 383 chevy, which will have a mech fuel pump.

    I’ve got a 3/8 hardline along the length of the chassis and my thinking is that I will need a filter between the tank and pump, a second filter between the pump and pressure regulator which will finally feed into the carb rail.

    This seems too simple to me, so am I missing something?

    Any info would be great fully received.

    Thanks
    Greg

    i'm fairly certain ours goes tank -> filter -> pump -> regulator -> carb rail. No additional filters in the circuit that i've ever seen or even aware off - lol. Never had a fueling issue due to any blockage related things either in nearly 10yrs.

    I've got an in-tank pump which has a crash filter to protect the pump from bits which then feeds onto the regulator via the main in-line filter.

    Thanks I'm hoping not to need an additional lift pump in the tank

    From the tank, I've put a pre-pump inline filter before the electric pump and an inline injection filter after up to a regulator in the engine bay.

    Is your piped barbed (after the pump) where it goes to flexy?

    It's not an additional lift pump, it's the one and only drive pump. Sits in a swirl pot fitted in the tank, no starvation issues!

    CPerry is this a question to me? If so I'm going to be using braided PTFE Teflon lined hose from Tourqes UK, along with their fittings through out.

    Alunwill thanks for the info, my tank will likely get the open cell foam baffling to help reduce starvation.
