Description
If you’ve been dealing with fuel contamination, mysterious engine hiccups, or just noticed diesel fumes around your tractor, there’s a good chance your fuel cap isn’t doing its job. A failing fuel cap lets in dirt, water, and debris while letting out expensive fuel—problems that’ll cost you way more than replacing the cap. This replacement cap seals up tight and keeps your fuel system running clean.
What You’re Getting
- Secure sealing system that keeps contaminants out and fuel vapors in
- Durable construction built to handle the bumps and vibration of field work
- Proper venting design that prevents vacuum buildup while maintaining seal integrity
- Direct OEM replacement—fits just like the original without modifications
Built for Real Farm Work
This cap is designed for Case CS and CVX series tractors along with Steyr’s 9000, 9100, CVT, and M series machines. These are serious work tractors used for everything from heavy tillage and planting to hay operations and livestock management. Whether you’re running a mid-size operation with a CVX or pushing big acreage with a Steyr M-series, clean fuel is critical for reliable performance.
Made to Last
Modern diesel injection systems don’t tolerate contamination, and this cap provides the first line of defense against dirt, water, and debris. The seal materials resist deterioration from fuel exposure and temperature extremes, while the cap body handles the daily abuse of farm work without cracking or warping.
Good to Know
Installation is straightforward—just unscrew the old cap and thread on the new one. If your current cap has been stuck for a while, a little penetrating oil around the threads helps. While you’ve got it off, take a look down the filler neck to make sure there’s no debris that needs cleaning out.
