The Motobilt relocation fuel tank moves the fuel tank from the center of the vehicle to the rear, behind the rear axle. Relocating the tank allows for more suspension and axle options as you upgrade your JK. This tank is designed to be completely bolt in and uses existing holes in your factory frame. No cutting of the frame is required. This tank is also compatible with the factory EVAP system so no tuning is required. The MB5034, included with the tank, will provide the necessary fuel lines and fittings to adapt it to your current emissions and fuel systems. We will also offer the EVAP kit as a separate product. The MB5032 fuel tank is designed to work with the factory fuel pump. The rear sway bar will need to be removed to use this tank.  

This tank allows you more options to modify your JK. With the tank relocated to behind the axle, you can use a 1 ton rear axle. Relocating the tank to behind the axle also allows use of a triangulated 4-link suspension setup. 

Designed as a heavy duty upgrade for the Jeep JK or JKU, this 22 gallon fuel tank features an all aluminum fuel cell constructed from 1/8” thick aluminum sheet that is precision CNC laser cut & CNC press brake formed. The tank is TIG welded for superior weld strength & weld finish. The fuel fill & vent tubes are CNC machined then TIG welded to the aluminum tank body. These machined parts are will still work with the factory fuel fill and vent.

The Motobilt JK Fuel Cell is fully protected by a heavy duty 3/16” steel skid. The steel skid is fully MIG welded & perfectly mounts to your stock JK frame. The aluminum fuel tank is secured to the steel skid using two steel hold down straps. 

We have included the Motobilt In Tank Fuel Pump Extension Kit for Jeep JK/JKU with this fuel cell along with the EVAP Kit. (see Specifications). There is no need to purchase it separately.
