490R Spin-On fuel filter/ water separators feature a hand (palm) operated fuel priming pump which simplifies service procedures and yields extremely low flow resistance due to its unique pump bypass characteristic.

These filters also feature multiple fuel ports (two inlets and two outlets) and a unitized mounting bracket for installation convenience. Inlet and outlet threads are 3/8”-18 NPTF (SAE J476). These filter assemblies provide flexibility during mounting to fit any engine application.
