This 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 that supports up to 550 hp 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. There also no need for the expense of a separate fuel pressure regulator and return line, the unit is internally regulated to 58 psi and excess fuel is returned withing the tank. The fuel level sending unit is pre-calibrated for use with a factory fuel gauge. It even includes a new lock ring and gasket.

Features:

  • 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
  • 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!
  • 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
  • Drops right into place of a stock fuel sending unit, just connect to factory hardline with EFI rated hose and clamps
  • Includes sending unit lock ring and o-ring
