FAQ
- Does this include the auxiliary install kit?
- No. This listing is the tank only. Order the gasoline hose & clamp kit and 1" filler-neck adapter separately.
- How does the AUX46RG connect to my truck?
- With an auxiliary kit that tees into the factory filler neck. The kit transfers fuel from the aux tank into the OE tank as you drive.
- What are the exact dimensions?
- Plan for 57" L x 12" W x 16.5–17" H. Some retailers list 16.5" body height; others round to 17". Leave clearance for the cap and mounting tabs.
- Is the interior baffled?
- Yes—fully welded baffles reduce slosh and improve stability.
- Is it DOT “refueling” approved?
- No—this is a gasoline auxiliary tank (meets 49 CFR 393.65). If you need to dispense fuel directly to equipment, see ATI refueling (transfer) tanks built under DOT special permits.
