Product Description
This tank is built to the original Willys Station Wagon design, quirks included — the fuel pickup tube sits on top rather than the bottom, and there's no vent neck, so it needs an in-line fuel filter and a vented gas cap to run correctly, just like the factory setup did. It ships complete with a 5-piece strap kit and a new sending unit gasket, cross-referenced to Willys part 906371.
Ethanol-blended modern fuel is harder on decades-old steel tanks than the gasoline they were designed around, accelerating the corrosion that eventually perforates the metal. Molded in cross-linked polyethylene, this replacement doesn't have that failure mode at all — it just needs to be the correct fitment, which is where the details below matter.

⚠ Compatibility Note: This tank has no vent neck by original design — an in-line fuel filter and vented gas cap are required and not included.
✓ 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.
