    Breakdown of Included Items

    Features:

    • Installs in most 7.500 in. to 12 in. deep factory fuel tanks or fuel cells to convert to an in-tank EFI fuel system
    • Ideal for Terminator EFI, Sniper EFI, MSD Atomic EFI, or any TBI EFI conversion
    • Horsepower ratings @ 60 PSI at 13.5 V / 16.9 AMP draw
    • The mounting surface is only 1.275 in. thick for a low-profile design and added clearance
    • An innovative clamping system for locating the module anywhere in the tank beside the existing sending unit
    • 360-degree rotating for easier clocking of the plumbing and wiring locations
    • The die-cast hanger bracket controls pump vibration

    Notes:

    • For installation, it is recommended to use a Holley 510-12-753 30 Amp Fuel Pump Relay and 12-gauge wire minimum size
    • Use only a maximum size of 6 AN for lines and fittings due to space limitations between unit and fuel tank
