Built for Real Farm Work
Your Massey Ferguson handles everything from tillage and planting to harvest and livestock chores. Whether you’re running a loader feeding cattle all day or pulling equipment during busy seasons, contaminated fuel can shut you down fast. This cap keeps your diesel clean and your tractor running, whether you’re parking in remote fields or storing equipment for the winter.
Made to Last
Cheap fuel caps crack, their seals fail, and their locks quit working right when you need them most. This cap uses quality materials that stay flexible in winter cold and won’t get brittle under summer sun. The seal holds up year after year, preventing moisture problems that lead to injector trouble and tank corrosion. The lock mechanism resists damage from fertilizer dust and road salt.
Good to Know
Installation takes just seconds – clean the tank neck threads with a rag before threading on the new cap to get a proper seal. If your old cap was leaking, check inside the tank neck for rust or debris. Keep your spare key handy but hidden – nothing’s worse than locking yourself out of your own fuel tank during planting season. Test the lock after installation to make sure it works smoothly.
