Built for Real Farm Work

This lockable filler neck fits a wide range of Massey Ferguson tractors from the classic 100 series models like the 165, 168, 185, and 188, through the reliable 200 series including the 290 and 298, up to the versatile 300 series tractors. These are the workhorses found on farms handling everything from row crop operations to hay work and livestock management, where keeping your oils clean and secure is essential for long-term reliability.

Made to Last

Quality materials resist corrosion and handle the constant exposure to weather, vibration, and temperature changes that come with agricultural work. The locking mechanism is built to withstand attempts at tampering while still giving you quick access when you need to check or add oil. The design maintains proper system function with correct venting that prevents pressure buildup while minimizing contamination.

Installation Notes

Installation is straightforward—just remove your existing filler neck and thread this one on in its place, and it comes with keys so you can keep a spare in a safe location. Make sure to test the locking mechanism after installation and keep those keys handy. A quick tip: if your old neck has been in place for years, a little penetrating oil around the threads makes removal much easier.
