Holley 255LPH OE tank style EFI fuel tank modules

APPLICATION: All gen 3, and 4 LS/Vortec engine swaps up to 550HP

PARTS INCLUDED: Varies by application

NOTES:  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! 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.
