Overview
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 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.

Samsonite? I was way off!
Size: 8, Color: Light Blue, Size: 8, Color: Light Blue
Linen was a nice enough material and slightly distracted from the dumb&dumber blue motif. The regular suit material would have been a full homage. It is what he wanted so this was a fair compromise. Stats/ he is a size 8 in most brands, 51in and 60lbs. Purchased an 8.
A size 7 would have been a better choice and more tailored look but this fit fine in the important places and he has room to grow. Short notice, quick shipping and fair quality for the price. May your Harry Dunne love it as much as mine did.
