ATI-ALUMINUM TANK INDUSTRIES

ATI – Aluminum Tank Industries at CPP Diesel

ATI (Aluminum Tank Industries) builds premium aluminum auxiliary and refueling tanks, combos, and severe-duty models for work trucks, ranch, farm, fleet, and overland rigs. Made in the USA, ATI tanks are built from thick aluminum, are fully baffled, pressure/leak-tested, and designed to integrate cleanly in full-size pickup beds with or without a crossover toolbox.

  • Proven constructions: .125" aluminum across core lines; heavy-duty Severe Series uses .190" aluminum.
  • Purpose-built shapes: L-shaped, rectangle, wedge, split-chamber, and tank/toolbox combos.
  • Refueling & Auxiliary solutions: Choose Refueling (TTL/TTR/TTW) for on-the-go equipment fueling under DOT special permit, or Auxiliary (AUX) to feed your truck’s factory tank via a filler-neck kit.
  • Accessory ecosystem: Pump kits, filter kits, caps, and install hardware to finish the job.

Which ATI Tank Do I Need?

Refueling tanks (TTL/TTR/TTW) let you legally refuel equipment when used under ATI’s DOT special-permit guidance and local regulations. Auxiliary tanks (AUX) gravity-feed your factory tank through a filler-neck adapter (Fuel Shotz kits available for common applications). If you carry a crossover toolbox, ATI’s L-shaped tanks tuck beneath it; if you need max capacity in a shorter footprint, go rectangle; for 5th-wheel/gooseneck clearance and rear visibility, choose a wedge; for two liquids, pick a split model; and for the toughest duty cycles or rocky job sites, select the Severe Series in .190" aluminum.

Frequently Asked Questions

What’s the difference between ATI refueling and auxiliary tanks?
Refueling tanks (TTL/TTR/TTW) are designed for dispensing fuel into equipment/vehicles under ATI’s DOT special-permit framework and local rules. Auxiliary tanks (AUX) feed your truck’s factory tank via a filler-neck adapter so the factory gauge stays full until the aux tank empties.
Do ATI tanks include pumps or install kits?
Refueling tanks ship as tanks; add a 12V transfer pump and hose/nozzle kit as needed. Auxiliary models may be sold tank-only or bundled with a Fuel Shotz install kit (e.g., AUX80LIKD for RAM 2013+). Check each product page for included items.
Will an L-shaped tank fit under my crossover toolbox?
Yes—ATI’s L-shaped geometry is built to sit beneath most crossover/chest toolboxes. Always verify bed/toolbox clearances and remember the cap height and mounting tabs when measuring.
Are ATI tanks baffled and pressure tested?
Yes. ATI tanks feature fully baffled interiors and are pressure/leak-tested for stability and safety.
What material thickness do ATI tanks use?
Core lines are built from .125" aluminum. Severe Series models upgrade to .190" aluminum for maximum durability.
Can I carry two different liquids in one tank?
Yes—choose a split model (e.g., TTL95S or TTR110S) with separate chambers and ports for two fuels/fluids.
