Holley Sniper offers OE-style 255 lph EFI fuel pump modules for a wide range of vehicles, including many Chevy, Pontiac, Buick, Oldsmobile, GMC, Ford, Mercury, Jeep, Dodge and Plymouth cars and trucks from the 1950s, '60s, '70s, and '80s. These in-tank modules are high-pressure units that flow 255 liters per hour (LPH) and are capable of supporting electronic fuel injection (EFI) engines producing up to 550 hp. A pre-calibrated fuel level sending unit designed to work with the factory fuel gauge for this application is included. Each 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 these modules return excess fuel right inside the tank! The Holley Sniper EFI fuel pump module was designed as a direct replacement for your factory pick-up and sending unit. There's 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.
