Behind the Seat Fuel Cell and Mount w/ Pump Cut Out Combo for Jeep YJ

Motobilt Inc Behind the Seat Fuel Cell and Mount w/ Pump Cut Out Combo for Jeep YJ is a purpose-built fuel tank solution designed specifically for Jeep Wrangler YJ builds that need improved clearance without giving up rear seat fitment. Unlike universal fuel cells, this contoured 18-gallon tank is shaped to maximize space behind the seat while working with the factory rectangular fuel pump cutout for a cleaner, more vehicle-specific installation.

Built from 1/8-inch aluminum, this fuel cell is CNC cut, press brake formed, and TIG welded for strength and durability in demanding off-road environments. It also includes a brass rollover valve with a 90-degree barbed hose fitting, a fuel pump extension bracket, and a large D-ring style cap for added convenience.

This combo package goes beyond the tank alone by including a dedicated mount system made to secure the fuel cell properly. The kit features a main under-tank plate, two clamp bodies, and mounting brackets to help create a stable, dependable setup. Ideal for YJ owners looking to stretch the wheelbase, improve ground clearance, or pair with a back-half kit, this made-in-USA Motobilt assembly delivers a smarter fit, rugged construction, and trail-ready performance.
