Product Description
The extended-range option for the same 1973-1981 full-size Blazer/Suburban/Jimmy platform as SKU 2225 — 31 gallons instead of 25, in a taller version of the same footprint. Cross-references to OEM part 475427, with a built-in fuel bowl, lock ring, and gasket included.
Old steel tanks don't just rust through the bottom — years of temperature swings work seams and welds loose too. This tank's one-piece polyethylene construction has no welded seams to fail, which is why an exact fitment match, not another round of patch repairs, is the real fix.

⚠ Compatibility Note: For 1982-1991 models, see SKU 2231A instead.
✓ 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.
