Description
Your Massey Ferguson 300 series tractor depends on clean fuel to keep running through long days in the field. A cracked or damaged fuel cap lets in dust, water, and debris that can clog your fuel system and lead to expensive repairs. This replacement cap seals tight and keeps contaminants out, so you can focus on getting work done instead of dealing with fuel problems.
What You’re Getting
- Essential protection that prevents fuel contamination and reduces evaporation
- Proper venting that maintains fuel system pressure without creating vacuum issues
- Non-locking design for quick refueling during busy farm operations
- Durable construction that handles farm conditions and temperature extremes
- Direct replacement – threads right onto your existing fuel tank
Built for Real Farm Work
This cap fits all the popular Massey Ferguson 300 series models – from the 340 and 342 utility tractors perfect for around-the-farm chores, to the bigger 398 and 399 machines that handle serious field work. Whether you’re running a loader, pulling implements, or doing haywork, this cap keeps your fuel system sealed and protected.
Made to Last
Quality materials stay flexible in winter cold and won’t get brittle under summer sun. The seal maintains its integrity year after year, preventing moisture infiltration that leads to fuel system problems and tank corrosion.
Installation Notes
Clean the tank neck threads with a rag before threading on the new cap to ensure a proper seal. Installation takes just seconds – unscrew the old cap and thread on the new one. If your old cap was leaking, check inside the tank neck for rust or debris that might prevent proper sealing.
