Holley/MSD is pleased to announce the release of OEM-Style EFI 255 LPH Fuel Tank Modules, which are a direct replacement for your factory pick-up and sending unit and make it easy to convert your carbureted fuel system to EFI. There's absolutely no need for any modifications or fabrication, and you don't have to get a whole new 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 EFI-rated fuel hose and hose clamps such as Earl's Vapor Guard. The in-tank fuel pump is a high-pressure 255 liter-per-hour unit capable of supporting EFI-equipped engines up to 550 horsepower. The module includes a pre-calibrated fuel-level sending unit designed to work with the factory fuel gauge already in your car or truck. You even get Holley's revolutionary HydraMat with a unique internal reservoir that keeps fuel available at the pickup and protects against contaminants. Fuel pressure is regulated internally and preset at 58 PSI, eliminating the added expense of an external fuel-pressure regulator and eliminating the need for a return line – all return fuel is handled right inside the tank.
