Product Description
Same dual-tank layout as the earlier Wagoneer/Cherokee (SKU 0020), updated for the 1978-1979 model years with different OEM part numbers — 8130368 and 8128589. Both lock rings, both gaskets, and the 3-piece strap kit are included in this one kit.
Steel OEM tanks corrode from the inside out as ethanol-blended fuel picks up moisture over the years, and once rust perforates the metal there's no patching it — a full replacement is the only real fix. This tank is molded in high-density cross-linked polyethylene specifically because it doesn't rust, pit, or corrode the way steel does, so once it's installed correctly it's not something you'll be revisiting.

✓ 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.
