Product Description
The 1978 model year used a rear-mounted vent pipe and no emission/rollover valve hole at all — the opposite configuration from the 1979 tank (SKU 4251A). Same 33-gallon capacity and footprint, cross-referenced to Ford part D8TZ-9002-B.
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: Rear vent pipe, no emission/rollover hole, specific to 1978. For 1979 (front vent, with EMS), see SKU 4251A.
✓ 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.
