Description

The Holley 12-329 Fuel Pump Module is an in-tank, high-pressure unit that flows 350 liters per hour (LPH) and is capable of supporting Electronic Fuel Injection (EFI) engines producing up to 750 horsepower. It includes a pre-calibrated fuel-level sending unit designed to work with the factory fuel gauge, solving common issues when converting from a carburetor to EFI. This module is a direct replacement that fits your factory fuel tank, eliminating the need to purchase a custom EFI fuel tank. You can even retain your factory fuel line by connecting the outlet of the pump module to the hard line on your vehicle with EFI-rated fuel hose and hose clamps.
