Installation Notes and Tips

Verify the filter dimensions before installation: 3.337 inches high, 4.959 inches long, and 3.703 inches wide. The bottom inner diameter is 0.25 inch and the top is closed, so confirm the housing and connection style match the existing fuel filter setup. Replace the filter at the OEM-recommended interval and prime the fuel system as required by the vehicle or equipment service procedure.
