  • Product Description

    Never hassle with transporting and transferring gas from gas cans again with the 20 gallon GenRight JK additional tank!

    This additional rear mounted tank is designed to occupy the rear space under the body where the factory muffler sits. This tank will give you a 600 mile range between fill ups! The extra 20 gallon tank increases your total capacity in a 4 door JK to 45 gallons!

    The nice part is you will not notice the extra gas tank since it is mounted under the body in the very rear of the vehicle and fills through the stock gas cap.

    It was specifically designed to be mounted under the rear cargo area of a Jeep JK so you can keep the center of gravity low!

    This tank follows in a line of innovative and trail proven heavy duty gas tanks produced by GenRight. 

    The tank is not a "transfer tank" it is a completely redundant tank with it's own fuel pump that is switched by you from the dash. Both tanks tie back into the factory fuel and emissions equipment so you won't get any check engine light or have computer issues.
