Fram Spin-on Fuel Water Separator Filter

The Fram Spin-on Fuel Water Separator Filter is structured for equipment that must keep fuel systems clear while maintaining steady throughput across variable load conditions. Standing 3.88" tall with a 3.81" outer diameter, it uses a threaded inlet and outlet arrangement that simplifies alignment on tight fuel rails or firewall-mounted brackets. The surface feels lightly textured, contributing to confident hand tightening without slippage. Inside, the separator elements divide water droplets from the fuel stream, helping reduce unwanted moisture that could otherwise influence combustion characteristics. Its internal pathways support consistent pressure behaviors across idling, acceleration, and towing situations. This Fram PS3808 offers a direct approach to keeping fuel delivery clean in diverse working environments.
