Gasket Fuel Sending Unit ; 45-53 Willys/Jeep Mode

The Gasket Fuel Sending Unit for 1945–1953 Willys and Jeep models is a critical OEM-spec replacement seal designed to prevent fuel leaks at the tank-mounted sending unit assembly. As any mechanic knows, a compromised gasket in this location doesn't just cause slow seepage—it risks raw fuel vapor escaping into the cabin and engine bay, creating both a fire hazard and a persistent fuel smell that no amount of detailing can mask. This cork gasket restores a leak-free seal between the sending unit flange and the fuel tank, ensuring accurate fuel gauge readings and safe fuel system operation on classic Willys and early Jeep CJ models.

Constructed from natural cork—the industry standard for fuel tank applications—this gasket features five mounting holes that align precisely with the original sending unit footprint. Cork's inherent resilience and fuel-resistant properties make it the preferred material for static seals in vintage fuel systems; unlike modern synthetics, cork conforms consistently to irregular tank surfaces and maintains integrity across temperature swings common in pre-1954 vehicles without sophisticated cooling. The 3.45 x 4.05 inch profile and minimal 0.02 lb weight ensure exact fit without modification, while the thin 0.5 inch gauge allows clean reassembly without shimming or forcing components.

Restoration shops and vintage 4x4 enthusiasts rebuilding 1945–1953 Willys MB or Jeep CJ platforms will find this gasket essential during fuel system rehabilitation. Installation is straightforward: remove the sending unit flange, scrape away the old cork, apply a thin bead of gasket sealant if desired for added security, and torque the five bolts evenly. Whether you're addressing a known fuel leak or performing preventative maintenance during a frame-off restoration, this OMIX-ADA gasket delivers OEM accuracy and reliability at a fraction of custom fabrication costs.
