All new Holley in tank Fuel Module with 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 (HP). If you are considering swapping your 68 - 72 Nova - Chevy II - to an LS or EFI setup, this is the sending unit for you! 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 Hydra Mat 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 1968 - 1972 GM X-body Nova 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 350 LPH fuel pump and a Holley Hydra Mat. Hydra Mat 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.
