    Holley 12-300 Details

    Converting the carbureted fuel system on your car or truck over to EFI has never been easier!Holley is excited to introduce our Holley OE style fuel tank modules that are designed as a direct replacement for your factory pick-up and sending unit. There is no need for modifications and you will not have to replace your fuel tank. You can even retain the factory fuel hard line, just connect the outlet of the pump module to the hard line on your vehicle with some EFI rated fuel hose and hose clamps such as the Earls Vapor Guard.
    • The in-tank fuel pump is a high-pressure 255-lph unit, capable of supporting EFI engines producing up to 550 horsepower
    • The module includes a pre-calibrated fuel-level sending unit that was designed to work with the factory fuel gauge already in your vehicle
    • Includes a Holley HydraMat with its unique internal reservoir, which keeps fuel available at the pickup while also providing protection from contaminates
    • Fuel pressure is regulated internally and preset at 58psi, eliminating the added expense of purchasing an external fuel pressure regulator
    • No return line needed. All return fuel is handled inside the tank
