Product Description
This dual fuel tank setup on early full-size Wagoneers and Cherokees means two lock rings and two gaskets to replace, and MTS includes both in this kit along with the 3-piece strap set. Cross-references to Jeep part numbers 8125733, 8126873, and 8127700, so you can confirm fitment against your VIN before ordering.
A pinhole rust leak in an old steel tank rarely stays a pinhole for long, and by the time it's obvious, the surrounding metal is usually too thin to weld safely. This polyethylene replacement sidesteps rust entirely, so the installation notes below are what actually determines whether this swap goes smoothly.

✓ 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.
