Filter P551435 is a separator element. It is typically mounted in a plastic housing with a sediment bowl. When replacing, it is worth getting a set of gaskets to avoid air entering the system.
Water in fuel is the main enemy of injection systems. If water appears in the sediment bowl under the filter, it must be drained immediately. Regular cartridge replacement prevents water from entering the injection pump and costly failures.
The filter separates water and solid contaminants.
