Holley EFI Fuel Pump - 525 LPH

This direct fit fuel pump will drop directly into any 1983-1997 Ford Mustang EFI fuel tank. The module has been designed with a 525 LPH (liters per hour) Holley fuel pump that will support up to 1200 EFI or 1450 Carbureted horsepower (HP Rating @ 60 PSI at 13.5 Volts / 17 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 1983-1997 Ford Mustang, we also offer a unit with a 340 LPH pump which supports up to 700 EFI or 900 Carb horsepower (12-345).
