All you had to do was go to Holley’s LSFest in Bowling Green to see just how popular the 1988 to 1998 GM C/K “OBS” trucks are right now. They were everywhere out there, with everything from stock LS engines swapped into them, all the way up to twin-turbo combos making 1,000 horsepower or more. Thanks to the fine folks at Holley you can now get these trucks, along with their Ford counterparts, capable of supporting big power while running the factory fuel tank.
Here is all the info from Holley:
This direct-fit fuel pump module will drop directly into any 1988-1998 GM C/K Series trucks and 1990-1997 Ford Truck EFI fuel tanks. 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 carbureted horsepower (@ 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.
