Titan Fuel Tanks has a 30-gallon auxiliary tank and fuel transfer control unit for diesel pickups that fits under the bed in the spare-tire stowage cavity. Claimed to be a first, the polyethylene tank fits most American-made diesel pickup trucks made after 1999.
 
The tank essentially doubles the fuel capacity of most pickups and, unlike in-bed auxiliary fuel tanks, its underbody location means that it leaves the entire the truck bed free for cargo, the company said.
 
The tank weighs 30 pounds and is easy for one person to install. A kit includes mounting hardware, a filler neck and cap, and an electronic fuel transfer unit that can be operated from inside the cab.
 
“Titan’s new Spare Tire Auxiliary Fuel System has tremendous potential, and is the most creative and efficient use of space I have seen,” Kyle Shiminski, category director, Keystone Automotive Operations, said in a statement.
 
“Diesel truck owners are always interested in extending their range and fuel capacity without compromising space in their trucks cargo bed and Titan’s new spare tire tank is an innovative solution to this challenge,” Paul Nishanian, executive vice president for Xtreme Diesel Performance, said in the statement.
 
Titan’s single-tank design fits in all intended applications, while mounting hardware unique to the host vehicle’s make and model allows the tank to securely attach to the cross members of the vehicle’s frame, the maker said. Mounting brackets attach easily and require no cutting, welding or drilling.
 
Like the spare tire it replaces, a mounting stud slides through the middle of the tank, which is then secured with a mounting plate. The additional fuel can be held in reserve or transferred on the go and as the need arises. The controller has an illuminated gauge and push button that starts and stops fuel transfers, or transfer stops automatically.
 
The tank’s military grade polymer material is highly resistant to the corrosive effects of diesel and bio-diesel fuels, as well as fuel additives that have been known to degrade the linings of steel diesel fuel tanks.
 
The tanks come with a universal filler kit featuring a brushed aluminum door that can be installed on the vehicle’s exterior sidewall or on an inside wall of the truck bed. The tanks include a rollover vent valve and a vent hose.
 
All Titan fuel tanks come with a limited five-year warranty. More information is at http://www.titanfueltanks.com.
