This direct fit fuel pump module will drop directly into any 1988-1997 GM C/K Series truck EFI fuel tank. The module has been designed with a 340 LPH (liters per hour) Sniper fuel pump that will support up to 700 EFI or 900 Carbureted horsepower (HP Rating @ 60 PSI at 13.5 Volts / 10.4 AMP Draw) We also have a 525 LPH module for the 1988-1998 GM C/K Trucks that supports up to 1200 EFI or 1450 Carb HP (@ 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.

Features:

  • The 6061-T6 Aluminum fuel pump module is a high-pressure unit that flows 340 liters per hour (LPH) and is capable of supporting EFI (electronic fuel injection) engines producing up to 700 EFI horsepower.
  • For the 1988-1998 GM Trucks, we also offer the unit with a 525 LPH pump which supports up to 1200 EFI horsepower
  • Includes a pre-calibrated fuel-level sending unit designed to work with the factory fuel gauge for this application
  • 6AN o-ring outlet and return ports for easy plumbing connections
  • Filter sock, flange O-ring, and fuel tank lock ring included to complete your installation
  • Can be used with both carbureted and EFI (Electronic Fuel Injection) fuel systems depending on your need
  • Both EFI and carbureted systems will need a bypass design regulator (We recommend the 12-879 or 12-880 Bypass Regulators for these installations. They can be used for both carbureted and EFI systems)
  • The flange is bright dip black anodized for corrosion protection from undercar moisture.
