Thread: Aftermarket fuel pump on Sniper EFI?

  1. #1

    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.

    This pump increases PSI as it slows down the flow rate. I was wondering if mine would do the same.
    Any EFI fuel pump will decrease volume output (GPH flow) as fuel pressure is increased.
