Drive All Day Without Worrying About Fuel Stops

If you’re clocking serious miles or running long hauls, the last thing you want is to be limited by fuel capacity. The Transfer Flow 100 Gallon In-Bed Auxiliary Fuel Tank gives you the kind of range that lets you skip the pit stops and keep rolling. Whether you're towing cross-country, heading into remote areas, or just want fewer interruptions on your route, this tank delivers peace of mind with every fill-up. With a 100-gallon diesel capacity, you’re looking at serious travel potential, more miles, fewer stops, and a smoother, more efficient drive. Even better, it fits snugly in your truck bed without getting in the way of your gear, tools, or fifth wheel hitch setup. The TRAX 4 system does all the fuel transferring for you, so you can focus on the road instead of constantly watching your fuel gauge. It’s made for drivers who don’t settle for stock range and want a solution that works as hard as they do.

Engineered To Perform When Miles Start Adding Up

Behind the scenes, this fuel system brings a lot of thoughtful engineering to the table. Built from powder-coated 12- and 14-gauge ReliaSteel, the tank is tough enough to handle heavy-duty use without rusting or warping over time. Inside, a baffled design helps reduce fuel slosh during cornering or uneven driving, keeping things stable and quiet. The TRAX 4 fuel management system is the real star here, it automates fuel transfers based on your main tank’s level, using sensors and AutoTrans technology to prevent overfilling or running dry. You can monitor everything right from your phone using the TRAX 4 app, or opt for an in-cab LCD screen for a quick glance at your fuel level. The system includes all necessary wiring, hardware, and brackets for a straightforward installation that works with 2008–2025 Ford, GM, and Dodge diesel trucks. It’s a purpose-built setup made for serious use, whether that’s on the job, off-grid, or hauling coast to coast.
