50-Gallon Auxiliary Fuel Tank

The KSH 50-Gallon Auxiliary Fuel Tank is designed to use the least amount of bed space while providing 50-gallons of additional fuel storage. 

The tank can be used as either an auxiliary diesel fuel tank or an auxiliary gas tank for the truck bed.

It is available in the standard and low profile models.  The Low Profile and Standard Model tanks are made of .125 gauge polished aluminum diamond plate. Other options are available upon request as outlined below.  KSH Auxiliary Tanks are made with two baffles to control fuel sloshing and to provide added stability.  The Standard Model is designed to be bed height so that it will not interfere with the operation of a 5th wheel. The Low Profile Model is designed to be used with trucks that have special requirements such as tonneau covers and roll top covers.

The KSH 50-Gallon Auxiliary Fuel Tank is designed to work in various models of Dodge, Ford, and General Motors Trucks. The tank will work with our installation kits, as well as our competitors.
