Aluminum Tank Industries AUX46R-B 46 Gallon Rectangular Diesel Auxiliary Fuel Tank Black Powder Coat

The Aluminum Tank Industries AUX46R-B is a 46-gallon rectangular diesel auxiliary fuel tank designed to significantly extend the driving range of diesel trucks. This tank features a durable black powder coat finish for enhanced corrosion resistance and professional appearance.

Constructed from heavy-duty .125" aluminum, this auxiliary tank is built to withstand demanding conditions on farms, construction sites, and over-the-road applications. Each tank undergoes meticulous weld inspection, pressure testing, and thorough cleaning to ensure reliability and safety.

Key Features:

• Dimensions: 57"L x 12"W x 16.5"H - fits most truck beds with adequate clearance
• Diamond plate aluminum construction with black powder coat finish
• Includes 3/8" NPT outlet, vent with rollover protection, automotive style fuel cap, and fully welded baffles
• Mounting tabs welded to tank for easy and secure bed installation
• Engineered to meet stringent D.O.T. requirements
• Baffled design reduces fuel slosh and adds structural strength
• Rollover and vent protection for enhanced safety

This auxiliary tank connects directly to your factory fuel tank through the factory filler neck, keeping your factory tank completely full until the auxiliary tank is empty. Installation requires a separate Fuel Shotz diesel auxiliary installation kit (sold separately), which uses a gravity-feed system with no wires or switches necessary. A valve at the tank allows you to cut off the fuel supply from your auxiliary tank if needed.
