Product Description
ATI AUX41RIK is a 41-gallon rectangular auxiliary diesel tank built from .125" diamond-plate aluminum and supplied with ATI’s filler-neck install kit. The system ties into the factory fill hose so the factory tank stays full until the auxiliary tank is empty—no wires or switches to install, with rollover protection on the tank and adapter.

FAQ
- How does the AUX41RIK system work?
- The install kit ties the auxiliary tank into the factory filler neck. The system maintains “full” in the OE tank and draws down the auxiliary tank first, with rollover protection at both the tank and adapter.
- Is this tank DOT compliant?
- Yes, ATI builds these auxiliary tanks to meet or exceed DOT standards, and each tank is pressure/leak tested. Use only as an auxiliary tank (not a refueling tank).
- Will it fit my Ford/Dodge/GM truck?
- Yes—choose the correct install kit for your model year in the options. Listings commonly cover 2011–current, with kits also available for earlier years.
- Are the interior baffles and rollover protection included?
- Yes. Tanks are fully baffled and include rollover protection; the install kit’s filler neck adapter also incorporates rollover protection.
- What exact dimensions should I plan around?
- Plan for ~48.5" (L) x 11" (W) x 19" (H). Allow extra for mounting tabs (~1.5" per side) and the cap (~2.5" taller).
