Transfer Flow 40 Gallon In-Bed Auxiliary Fuel Tank System - TRAX 4 (MPN: 0800116637)

Description

The 40-Gallon Auxiliary Fuel Tank System – Unmatched Compatibility and Convenience

Take your truck further with Transfer Flow’s 40-gallon in-bed auxiliary fuel tank, the most universally compatible fuel tank available. Designed to fit half-ton pickups, trucks with utility beds, RamBox-equipped models, and vehicles with a factory-installed 5th-wheel prep package or other 5th-wheel hitch, this tank is built for maximum versatility. Its low-profile design allows it to fit seamlessly under most standard tonneau covers, keeping your bed space free for cargo and gear.

Powered by Transfer Flow’s patented TRAX 4™ operating system, this auxiliary fuel system offers computer-controlled automatic fuel transfers—safer, smarter, and more reliable than traditional gravity-fed systems. TRAX 4™ monitors both your main tank and auxiliary tank, transferring fuel at predetermined levels while your truck is in operation. For added convenience, the TRAX 4™ mobile app lets you monitor your fuel levels in real-time from your smartphone, giving you complete control over your fuel supply wherever the road takes you.
