Want an extra capacity fuel tank for your gas guzzling CJ? Check out this 21-Gallon plastic fuel tank designed to replace a 15-Gallon fuel tank; hangs 4″ lower than the original tank. Includes new sending unit, top strap, lock ring, O-ring, and skid plate extensions. These tanks are made in the USA. Dimensions 23" x 16" x 15". This does not include a skid plate. Fits:

  • Jeep CJ-5 (1978-1983).
  • Jeep CJ-7 (1978-1986).
From 1981-1986, Jeep® offered an OEM 20 gallon factory "plastic" tank in the CJ's. Our 21 gallon tank does not directly replace the OEM 20 gallon factory plastic tank. A new 15 gallon OEM style skid plate, end straps and hoses are required to install this 21 gallon tank. Note: Will not fit CJ-8 Scrambler.

Hits my differential cover

Shipped fast and easy to install, But it rest on my differential cover, I’m going to have to move my rear end forward and change pinion angle just to get a little bit of clearance, my rear end is currently centered in wheel well, and has a 4” suspension lift and a 2” body lift so I was not expecting to have clearance issues! I will try moving the rear end forward but if it doesn’t give me enough clearance I will have to remove this new tank and put the 15 gallon tank back in.
