What’s Included
- ATI 43-gallon rectangular auxiliary tank (AUX43R)
- Fuel Shotz diesel install kit (hoses, clamps, adapter, shutoff valve)
How the Fuel Shotz System Works
The auxiliary tank connects to your factory filler neck. It keeps the factory tank at “full” until the auxiliary tank is empty; then your OE gauge drops from full. Gravity feed means no electrical switches. Rollover valves are integrated for safety.
Compliance
Meets applicable DOT requirements for auxiliary diesel systems when installed and used as directed (gravity feed to filler neck with rollover protection). Follow all federal/state/local regulations.
Installation Notes
- Install shutoff valve at tank outlet; route hose through a 7/8" bed grommet to the filler-neck adapter.
- Fill the factory tank first, then open the auxiliary shutoff and leak-check the system.
- Bolt tank through welded tabs to the truck bed per ATI guidance.
