Product Description
Unlike the 21-gallon upgrade tank for this same body style (SKU 0051XL), this 15-gallon version is a straightforward bolt-in that also fits the CJ8 Scrambler, which the taller XL tank cannot. Cross-references to Jeep part number 8128585, and comes with a new lock ring and gasket.
A tank this old has usually already sprung one leak or been patched at least once, and every patch job is just delaying the next one. Cross-linked polyethylene construction sidesteps that cycle entirely — the material doesn't corrode, so getting the fitment and installation details right matters far more here than any patch repair ever could.

✓ Appearance Note: Because each tank is custom molded, you may occasionally notice minor cosmetic surface bubbles left over from the molding process. This is purely cosmetic, has no effect on performance or durability, and doesn't occur on every unit — every tank is individually pressure-tested before it ships to confirm a leak-free seal.
⚠ Order Notice: MTS builds each fuel tank to order rather than pulling from mass-produced stock. Please allow a 7–10 business day lead time for manufacturing and individual pressure testing before your tank ships.
