Overview

This 37-gallon in-bed auxiliary diesel fuel tank is designed for short and long bed pickups, fitting under most retractable and standard tonneau covers. It features the TRAX 4™ system for automatic fuel transfer, monitoring both main and auxiliary tanks and transferring fuel at pre-set levels. The TRAX 4 mobile app allows users to track fuel levels, calculate miles-to-empty (MTE), and oversee transfers from a smartphone.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Free shipping over $200 in the continental US. Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
