Description
When you’re changing the fuel filter on your Fiat tractor and that old banjo bolt looks corroded or won’t seal properly, you know it’s time for a replacement. This little bolt might seem simple, but it’s critical for keeping fuel flowing cleanly to your injection system without leaks. A damaged banjo bolt can cause air to get into the fuel lines, leading to hard starts and rough running you don’t need when there’s work to do.
What You’re Getting
- M14 metric thread that matches your Fiat’s fuel filter housing perfectly
- Proper sealing design that keeps fuel in and air out of your fuel system
- Quality construction that handles the pressure and vibration of diesel fuel systems
- Direct replacement bolt that installs just like the original
Built for Real Farm Work
This banjo bolt is specifically designed for Fiat 90 Series tractors like the 100-90 and 110-90 models. These are solid utility tractors that see a lot of loader work, hay cutting, and general farm duties where reliable fuel flow matters.
Made to Last
This bolt is built to handle the constant pressure cycling and vibration that comes with diesel fuel systems. The proper metallurgy resists corrosion from fuel exposure, and the threads are precision-cut to seal properly without over-tightening.
Installation Notes
Thread this bolt in snug but don’t over-torque it—the sealing washers do the work, not brute force. Always use new sealing washers when installing a new banjo bolt to prevent leaks. A small amount of diesel-rated thread sealant helps ensure a lasting seal.
