Low Profile Fuel Tanks for Truck Bed

Browse our selection of low profile transfer tanks, auxiliary tanks and tank toolbox combos for sale. Low profile tanks are designed with lower heights that are below your bedrails. Many transfer tanks have a fuel pump that sits on top of the tank. We have a few options that allow your tank and pump to sit under a truck bed cover:

  • ATI Tanks - Add the "ATI Tank Notch for Tonneau Cover" modification. This is found as an add on option for ATI's transfer tanks.
  • Transfer Flow - The Transfer Flow Under Tonneau Cover Tank includes a side holstered pump that sits below your tonneau cover.
  • ATTA - Offers a transfer tank with a lower height fuel bung design. This allows the tank and the fuel pump to sit below the tonneau cover.

If you have any questions about finding the right fit, you can call us at 800-964-5341 or use our contact form to ask a question.
