Product Description
ATI AUX42RIK is a 42-gallon rectangular auxiliary diesel tank built from .125" diamond-plate aluminum and paired with ATI’s Fuel Shotz install kit. The kit ties into the factory filler neck so the auxiliary tank keeps the OEM tank topped off until it’s empty—no wires or switches required. Fully baffled, pressure/leak-tested, and DOT-compliant for on-road use.

FAQ
- Does AUX42RIK actively transfer fuel to the engine?
- No. The Fuel Shotz system ties into the factory filler neck and keeps the OEM tank full. When the auxiliary tank empties, your factory gauge moves off “Full.”
- Is wiring required for the install?
- No wiring or switches are needed with the Fuel Shotz kit—one reason installs are quick.
- What fuels are supported?
- Designed for diesel use as an auxiliary pickup bed tank.
- Will it fit my truck?
- Fitment is broad with the correct kit. Common support includes Ford, Chevy/GMC 2011+, and Dodge through 2012. Verify your year/make on the product page and confirm bed/toolbox clearances.
- What are the exact dimensions?
- Plan around 48.5" L x 19" W x 12" H overall for the tank body.
