Why would I relocate the fuel tank on a Jeep Gladiator?
Once a Gladiator moves into a double triangulated rear 4-link suspension, the factory fuel tank occupies the same space needed for proper link geometry. Relocating the fuel tank creates room for the suspension links, improves packaging, and allows the rear suspension to function without compromise.
How much fuel does the MB5083 hold?
The MB5083 holds approximately 25 gallons of fuel, providing roughly 3 additional gallons over the factory Gladiator fuel tank while relocating the fuel load to a more suspension-friendly location.
Is this fuel tank designed for linked rear suspension systems?
Yes. The MB5083 was specifically designed to support double triangulated rear 4-link suspension layouts where the factory fuel tank interferes with link placement and suspension geometry.
Can I reuse my factory fuel pump?
Yes. The MB5083 is designed to reuse the factory fuel pump assembly, helping maintain factory fuel system functionality and serviceability.
Does this system retain the factory EVAP system?
Yes. The tank is designed to work with the factory EVAP components. An EVAP relocation bracket is included and must be welded to the crossmember during installation.
Can this tank be used with a factory frame?
Yes. The MB5083 can be installed on a factory uncut Gladiator frame or as part of a Motobilt bobbed bed build.
What modifications are required for installation?
Installation requires removal of the factory fuel tank, removal of the rear track bar mount, and removal of the rear-most factory crossmember. Welding is required to install the included EVAP relocation bracket.
Will this work with a Motobilt bobbed bed?
Yes. The MB5083 was designed to work with the Motobilt bobbed bed system. However, a receiver hitch cannot be used when installed with a bobbed bed configuration.
Is the fuel tank protected for off-road use?
Yes. The aluminum fuel tank is protected by a 3/16-inch steel skid plate designed to shield the tank from trail obstacles and off-road impacts.
Is this a bolt-on installation?
No. This system is intended for experienced fabricators building linked rear suspension systems. Cutting, component removal, and welding are required during installation.
What suspension systems is this tank commonly used with?
The MB5083 is commonly used on Jeep Gladiator builds utilizing double triangulated rear 4-link suspensions, rear frame modifications, bobbed bed conversions, and other suspension layouts where the factory fuel tank limits packaging and clearance.
Why is the tank mounted behind the rear axle?
Moving the fuel behind the axle frees up the space between the frame rails that is typically occupied by the factory tank. This allows builders to properly package suspension links, shocks, crossmembers, and other components required for advanced rear suspension geometry
