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.

Holley boost control solenoids are designed for optimal performance when using the boost control function of Holley EFI. Some setups require two solenoids and some require one. They're driven by a Pulse Width Modulated (PWM) output of the ECU. It is advised NOT to use the PWM+ outputs on a Holley HP ECU, but rather use the PWM- outputs. If you have a Holley Dominator ECU, use either the PWM- outputs or a PWM+ output on the J2B connector.
