*** In 1987 there was a change to TBI fuel injection on some of the square body trucks and this change included the addition of this baffle in the fuel tank. These pump modules will not work with baffled EFI tanks. *** Our module was designed and oriented for the passenger side fuel tank that was the default location for single tank application models. To use the same module on the driver's side tank, you will have to lengthen your fuel hoses/lines to connect to the module because of the outlet orientation.

Overview

• 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 • 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 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 1973-87 GM C/K Series Muscle Truck 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.
