ATI AUX43RIKD is a Ram-specific 43-gallon rectangular diesel auxiliary tank bundled with ATI’s Fuel Shotz install kit. Built from .125" bright aluminum and fully baffled, it ties into the factory filler-neck hose so your factory tank stays at FULL until the auxiliary tank is empty—no wires, switches, or dashboard mods required.

FAQ

Will AUX43RIKD work on my Ram?

Yes—this SKU is packaged with the Ram-specific Fuel Shotz kit for Ram diesel 2013–current (some listings show 2012+). Verify your filler-neck style before purchase.

How does the auxiliary tank keep my factory tank full?

The Fuel Shotz system connects at the factory filler-neck hose. As you drive, fuel gravity-feeds to the OEM tank; your gauge stays on FULL until the auxiliary tank is empty.

Do I need wiring or a dash switch?

No. The system is purely mechanical—no wiring or switch required.

What are the exact dimensions?

Approx. 58" L x 12" W x 16.5" H (some spec tables round height to ~17"). Mount brackets can add ~1.5" per side; allow clearance for the cap.

Is the tank baffled and pressure-tested?

Yes. Tanks are fully baffled to reduce fuel movement and are visually, pressure, and leak-tested before shipment.
