Description
You know how important your fuel system is—when seals start leaking around the injection pump, you’ll notice diesel fuel drips under the tractor or smell fuel in the cab. Injection Pump O-Ring $21.29 SKU: QTP-56655 This little seal keeps pressurized fuel where it belongs and prevents air from getting sucked into the system, which can cause all sorts of running problems.
What You’re Getting
- Exact fit replacement that seals properly against high pressure diesel fuel
- Quality rubber compound that handles fuel exposure and temperature changes without breaking down
- Direct drop-in replacement—no modifications needed for your Fendt injection pump
- Prevents both fuel leaks and air intrusion that causes poor performance
Built for Real Farm Work
This O-ring fits several Fendt series including the Farmer 400 Vario models, Favorit 700 series, and Farmer 300 C/CA tractors. Whether you’re running a mid-size utility tractor or a larger field machine, these Fendts are known for their reliability when properly maintained. Consider replacing the injection lines and seals at the same time since you’ll have everything apart anyway.
Made to Last
Fuel system seals take a beating from high pressure, temperature swings, and constant exposure to diesel fuel and additives. This O-ring is designed to handle the demands of modern diesel fuel formulations, including biodiesel blends that can be hard on rubber components.
Good to Know
Have plenty of rags ready – fuel will drain from both ends when you disconnect the old line. Clean all connection points thoroughly before installation; any dirt here goes straight to your injection pump. When replacing this seal, take a good look at the mating surfaces for any nicks or corrosion that could prevent proper sealing.
