3. The really cool part about S&P's replacement fuel cell is that you can ditch the one that originally sat behind the factory bench seat. That adds precious cargo room inside the cab. But, this cell also features the correct sending unit to work with your fuel level gauge, ports for return and supply lines, and an in-tank electric fuel pump. Don't forget you'll need to shave the fuel filler hole in the rear cab pillar if you swap tanks.
