Holley EFI Fuel Pump Module - 525 LPH

This direct fit fuel pump module will drop directly into any 1988-1998 GM C/K Series truck EFI fuel tank. The module has been designed with a 525 LPH (liters per hour) Holley EFI fuel pump that will support up to 1200 EFI or 1450 Carbureted horsepower (HP Rating @ 60 PSI at 13.5 Volts / 16.9 AMP Draw). The flange has a 6AN o-ring outlet and return port making the plumbing connections easy. The kit includes the assembled module, a new filter sock, flange o-ring, and the lock ring to complete your installation into your stock fuel tank. The 6061-T6 module flange has been anodized in a bright dip black finish that not only looks great but will also protect from undercar corrosion.

For the 1988-1998 GM C/K Trucks, we also have a 340 LPH module (12-353) that supports up to 700 EFI or 900 Carb HP.

Bypass fuel pressure regulator required; 12-879 or 12-880 regulators recommended.
