If you've ever noticed fuel fumes in the cab or spotted diesel on the ground under your tractor, you know how important a good fuel cap is. This vented metal fuel tank cap for David Brown, Massey Ferguson, Case IH & Ford tractors keeps your fuel system sealed up tight while letting the tank breathe properly. When your old cap starts leaking or won't stay tight, it's time to swap it out before you end up with contaminated fuel or worse—an empty tank from spillage. What You're Getting Durable metal construction that won't crack like plastic caps after a few seasons of sun and weather Proper venting system that prevents vacuum buildup while keeping dirt and moisture out of your tank Secure threads that won't strip out or come loose during field work Weather-resistant design built to handle everything from winter cold to summer heat Direct replacement that threads right on—no modifications needed Built for Real Farm Work This cap works across many popular tractor brands including Massey Ferguson, Ford, Case IH, and David Brown tractors used for hay operations, planting and cultivating, or loader work and property maintenance . Whether you're running a compact utility tractor for daily chores or a larger machine for serious field work, this cap handles the bumps, vibration, and weather that comes with farm life. Made to Last The metal construction gives you years of reliable service that plastic caps just can't match. The seal maintains proper tank ventilation while keeping contaminants out, and UV-resistant materials won't get brittle and crack after a few seasons in the sun . This cap stays flexible and keeps sealing season after season. Good to Know Installation is straightforward—just thread it on until the gasket seats firmly. Don't overtighten, as this can damage the seal and make future removal difficult. Check that the old gasket isn't stuck to the tank opening before installing the new cap . A quick wipe of the threads with a rag helps ensure a clean, tight seal.
