Lower fuel costs and increase your driving range with the RDS 60-Gallon Auxiliary Diesel Fuel Tank. This auxiliary fuel tank mounts behind the cab in your pickup. Made of no-rust diamond tread plated aluminum with internal baffles to reduce slosh, this fuel tank includes a secure fill compartment to prevent theft and a manual sight fuel gauge. Easily connects to pickup’s fuel line using optional install kit (sold separately).
NOTE: For safety reasons, the filler neck on RDS fuel tanks prevents them from being overfilled. Actual usable tank capacity is about 95% of the total advertised gallons due to fuel expansion in warmer climates.
