Product Description
An early, short-lived K5 Blazer/Jimmy configuration with a 1.25" filler neck O.D. — worth measuring before ordering, since MTS notes to call and confirm fitment on this one. Mounts inside the frame with a new lock ring and gasket included.
By the time a steel tank rusts through, the fuel it's been holding has usually already picked up rust flakes that foul filters and injectors downstream. Swapping to this polyethylene tank removes that source of contamination for good, provided the capacity and mounting details match your application exactly.

⚠ Compatibility Note: Confirm fitment with MTS before ordering — call to verify against your specific truck.
✓ 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.
