Holley's all-new Universal In-Tank Retrofit Fuel Modules – available in both return-style and returnless configurations – eliminate the burden of converting a factory tank or fuel cell for an in-tank EFI fuel system. Both versions are available with your choice of two fuel-pump options – 255 lph or 450 lph – for a wide variety of applications. Both come complete with the innovative Holley HydraMat system already installed to handle fuel-pickup. Returnless modules include all the features of a standard return module and eliminate the need for a return line and a conventional pressure regulator. Once installation is complete, all that remains is fuel-line routing and connecting the power source and ground. A vibration-resistant clamping system and integrated fuel pump make it easy to locate the module anywhere in the tank and rotate the unit a full 360 degrees for unlimited plumbing and wiring clocking. All-aluminum construction and black anodizing make for great looks and maximum corrosion-resistance, and ¼-inch NPT ports create an endless array of plumbing options.
