Part No: SK5501
Fits: Universal — Ford Powerstroke, GM Duramax, Dodge RAM Cummins

What It Does
- No tank drop. A single drilled hole and one bolt. The bed stays on the truck.
- Draws from the bottom. Suction port sits at the lowest point in the tank.
- Kills quarter-tank fuel starvation. No more supply issues when the gauge gets low.
- Reservoir effect. The oversized bowl keeps fuel at the pickup under hard braking and acceleration.
- Plumbed return. A 1/2" NPT return port lets you run the FASS return line straight back to the sump.
