Thread: Aftermarket fuel pump on Sniper EFI?

    Default Aftermarket fuel pump on Sniper EFI?

    I currently have a Mr. Gasket 105 GPH fuel pump on my '84 Z28 feeding a stock Chevy TPI 350. I'm planning on swapping this system and I'm wondering if my pump will work with the system? Pump:

    I would say NO, that pump is for carbureted 14 psi. You would need an EFI pump, which has a pumping pressure of 60 psi.

    This is the pump included with the master kit:
    This pump increases PSI as it slows down the flow rate. I was wondering if mine would do the same.

    I would say since it says "maximum" psi of 14, that no, it wouldn't work.

    Yes, the Holley 12-920 or 12-800 is the EFI fuel pump you need for 43-60 psi.
    EFI fuel pumps have a wide range of psi capability; you set the exact pressure you need/want.
    Electric fuel pumps only produce volume, the fuel pressure regulator creates the desired pressure.

    Any EFI fuel pump will decrease volume output (GPH flow) as fuel pressure is increased. (Fuel System Selection Chart)
