This fuel filter is a genuine AGCO component that removes contaminants from the fuel supply before it reaches the injection system. It is installed in the fuel line between the tank and the high-pressure pump, where it protects the injectors and pump internals from abrasive particles and water. A restricted filter reduces fuel flow, causing hard starting, power loss, and erratic engine operation. The filter housing and seal geometry are matched to the original assembly to maintain proper sealing pressure and prevent air ingress into the fuel system. When replacing, ensure the housing is clean and the seal is seated correctly before tightening to the specified torque.
