International Engs, Trucks
Designed for cartridge-style fuel modules on International trucks, the Baldwin Fuel Water Separator Filter provides controlled water separation without changing factory service procedures. The filter installs directly into the existing housing, where its molded end caps create a tight interface that limits fuel from slipping past the element. Inside, the filtration media is arranged to separate water while managing heavier debris, helping fuel delivery remain consistent as service hours accumulate. The pleated structure is supported to hold its form under normal operating suction, which helps preserve flow as contaminants build within the element. Regular service with the correct cartridge keeps fuel quality stable and avoids issues tied to moisture entering the system. This Baldwin PF7978 filter fits the module as intended and supports dependable day-to-day operation.
