Holley Sniper EFI 12-317 In-Tank EFI Fuel Pump Module 255 LPH

Compatible with 1961-1964 Chevrolet® Impala® / Bel Air / Biscayne. This product is not created or sold by Chevrolet®.;

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.;
