This in-tank fuel pump module is a high-pressure unit that flows 255 liters per hour (LPH) and is capable of supporting electronic fuel injection (EFI) engines producing up to 550 horsepower. Featuring 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 contaminates. The fuel pressure is internally regulated to 58 psi eliminating the added expense and effort of purchasing and installing an external fuel pressure regulator - no separate return line is required because this module returns excess fuel right inside the tank! This 1963-1967 Corvette Muscle Car EFI Fuel Pump module was 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.

The pump is not compatible for use with PWM (Pulse-width Modulation) The 63-67 Corvette's fuel gauge converts a voltage into a level reading rather than resistance like most cars. For this reason the yellow wire needs to be wired to switched ignition. The factory operated this way as well. This wire can be attached to Wire A on the diagram attached that connects to the "S" terminal on the factory module
