Holley Efi Fuel Pump Module - 255 Lph - 78-81 Corvette

This in-tank fuel pump module is a high-pressure unit, capable of flowing 255 liters per hour (LPH) and supporting electronic fuel injection (EFI) engines with a power output of up to 550 horsepower. It comes equipped with a pre-calibrated fuel-level sending unit designed to seamlessly integrate with the factory fuel gauge for this specific application. Additionally, the module features a HydraMat filter with a unique internal reservoir that ensures a consistent fuel supply at the pick-up point while offering protection from contaminants.

The fuel pressure is internally regulated to a steady 58 psi, eliminating the added expense and effort associated with purchasing and installing an external fuel pressure regulator. Notably, no separate return line is required, as this module efficiently returns excess fuel directly inside the tank! Specifically designed as a direct replacement for the factory pick-up and sending unit in 1978-1982 Chevrolet Corvettes, this module eliminates the need for a custom EFI fuel tank. Furthermore, you can retain the factory fuel hard line by connecting the outlet of the pump module to your vehicle's hard line using EFI-rated fuel hose and hose clamps readily available in the Earls Vapor Guard line. This Muscle Car EFI Module includes a 255 LPH fuel pump and incorporates the innovative Holley HydraMat—a patent-pending fuel reservoir system that effectively addresses fuel starvation concerns during maneuvers such as cornering, acceleration, braking, incline traversal, and in low fuel conditions.
