Product Details

Fuel Pump - Electric - In-Tank - 255 lph - Chevy Corvette 1975-77 - Each

OEM Style EFI Fuel Tank Modules; 255 LPH; Incl. Fuel Level Sending Unit/Hydra Mat/Internal Fuel Pressure Regulator;

This 1975-77 Corvette Muscle Car 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 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.
