Nissan Technical Advisor 3/22/2011Relieve fuel system pressure by removing the fuel pump fuse and running the engine or connecting a fuel system pressure relieving tool to the shrader valve on the fuel rail. Raise and support the vehicle safely. Remove the fuel filter mounting bracket retaining nuts then loosen the filter retaining clamp and slide the bracket assembly back to provide better access to the push connect fittings. With a rag positioned to catch any spilled fuel, dis-engage the retainer clip and remove the line. Detach the fuel lines from both ends of the fuel filter by disengaging both push connect fittings. Install new retainer clips in each push connect fitting. Note which way the flow direction arrow points on the old filter. Remove the filter from the bracket by loosening the filter retaining clamp enough to allow the filter to pass through.
Install the filter in the bracket, ensuring proper direction of flow as noted by arrow. Tighten clamp to 15–25 inch lbs. Install the push connect fittings at both ends of the filter. Lower the vehicle. Start the engine and check for leaks.
