Holley – OEM Style EFI Fuel Tank Module

Description

The Holley 12-303 OEM Style EFI Fuel Tank Module is a high-pressure in-tank unit flowing 255 LPH and supporting EFI engines up to 550 HP. Designed as a direct replacement for the factory pick-up and sending unit on the Chevrolet Monte Carlo and Pontiac GTO, it eliminates the need for an external fuel pressure regulator with internal regulation at 58 PSI, requiring no separate return line. The integrated HydraMat filter keeps fuel available at the pick-up while protecting against contaminants. The pre-calibrated sending unit (0–90 ohms) works with the factory fuel gauge. No custom EFI fuel tank required; the factory fuel hard line can be retained.
