Holley Efi Fuel Pump Module - 255 Lph - 61-64 Gm B-Body

This in-tank fuel pump module operates as a high-pressure unit, delivering a flow of 255 liters per hour (LPH) and supporting electronic fuel injection (EFI) engines with a capability of up to 550 horsepower. The fuel pressure is internally regulated to a steady 58 psi, eliminating the need for an additional 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. The module includes a pre-calibrated fuel-level sending unit, meticulously designed to seamlessly integrate with the factory fuel gauge for this specific application. Additionally, this module features a HydraMat filter equipped with a unique internal reservoir, ensuring a consistent fuel supply at the pick-up and providing protection from contaminants.

Specifically crafted as a direct replacement for the factory pick-up and sending unit in 1961-64 Chevrolet Impala/Bel Air/Biscayne Muscle Cars, this EFI Fuel Pump module eliminates the need for a custom EFI fuel tank. Retaining the factory fuel hard line is easily achievable—simply connect 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 incorporates a 255 LPH fuel pump and integrates the innovative Holley HydraMat—a patent-pending fuel reservoir system designed to mitigate fuel starvation issues during various driving scenarios, such as cornering, acceleration, braking, incline traversal, and low fuel conditions.
