In-Tank Retrofit Fuel Pump Module
Product Information
Holley in-tank retrofit fuel modules are the easiest way to convert your vehicle's factory tank or fuel cell to an in-tank, EFI fuel system—and gain all the benefits of a Holley Hydramat reservoir, as well. This conversion requires only basic tools, no welding or fabrication. The low-profile, aluminum module design includes a billet pump hanger bracket to control vibration; Holley's innovative clamping system and integrated fuel pump allow you to locate the module anywhere in the tank beside your existing sending unit. Once installed, simply hook up your fuel lines and your power source/ground, and you're ready to roll. Holley in-tank retrofit modules are available with fuel pumps for both return and returnless-style systems—and models to support various liters per hour (LPH).
