1978-1981 Chevrolet Corvette Muscle Car EFI Fuel Pump Module


This in-tank fuel pump module is a high-pressure unit that flows 255 liters per hour (LPH) and is capable of supporting EFI (electronic fuel injection) engines producing up to 550 horsepower • Fuel pressure is internally regulated to 58 psi eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator • A pre-calibrated fuel-level sending unit designed to work with the factory fuel gauge for this application is included • This module also features a HydraMat filter which has a unique internal reservoir that keeps fuel available at the pick-up and also provides protection from contaminants .

This 1978-1981 Chevrolet Corvette Muscle Car EFI Fuel Pump modules are designed as a direct replacement for your factory pick-up and sending unit. There is no need to purchase a custom EFI 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 available in the Earls Vapor Guard line. This Muscle Car EFI Module includes a 255 LPH fuel pump and a Holley HydraMat. HydraMat is an amazing patent-pending fuel reservoir system that reduces fuel starvation issues that might otherwise occur while cornering, accelerating, stopping, traversing inclines, and during low fuel conditions.
