This fuel filter set removes particulate and water from the fuel supply before it reaches the injection system. The filters sit in the housing on the engine’s fuel line, where they protect the high-pressure pump and injectors from abrasive contaminants. A restricted filter reduces fuel flow, causing power loss and hard starting; a fully clogged element can starve the engine and lead to injector damage. The set is manufactured by AGCO, and the assembly matches the original housing’s seal geometry so the bypass valve seats correctly and filtration pressure is maintained. On reinstall, replace any housing seals and tighten the cap to the specified torque.
