#### REMOVAL & INSTALLATION

Datsun/Nissan recommended if the vehicle is operated under extremely adverse weather conditions or in areas of extreme high or low ambient temperatures the fuel filter may become clogged. Is so, replace the fuel filter immediately. The fuel filter and fuel lines should be inspected 30,000 mile or 24 months. Check fuel lines and fuel tank assembly for proper attachment to the vehicle. Check fuel lines and filter for leaks, cracks, damage or loose connections.

The fuel filter on all models is a disposable or replaceable unit if necessary. Most models the fuel filter is located in the engine compartment (refer to the illustrations) on the right inner fender well. On the Stanza wagon, the fuel filter is found inline, outside the vehicle under the floor, near the fuel pump assembly.

NOTE: A DIRTY FUEL FILTER WILL STARVE THE ENGINE AND CAUSE POOR RUNNING!

CAUTION
If equipped with an Electronic Fuel Injected (EFI) engine, refer to the "Fuel Pressure Release Procedure'' in this section and release the fuel pressure before removing filter. OBSERVE ALL NECESSARY SAFETY PRECAUTIONS. READ THE COMPLETE SERVICE PROCEDURE BEFORE STARTING THIS REPAIR.

1. Release the fuel pressure. Disconnect the negative battery cable. Locate fuel filter on right-side of the engine compartment and place a container under the filter to catch the excess fuel.

   NOTE: On the Stanza wagon, the fuel filter is found inline, under the floor, near the fuel pump.

2. Disconnect the inlet and outlet hoses from the fuel filter. Make certain that the inlet hose (bottom) doesn't fall below the fuel tank level or the gasoline will drain out.
3. Remove the fuel filter from its clip and replace the assembly.

   To install:

4. Replace the inlet and outlet gas hose lines if necessary. Install the fuel filter assembly in place, always replace the gas hose clamps on EFI models. Tighten hose clamp so that clamp end is 3mm from the hose end.

   NOTE: Ensure that the screw does not contact adjacent parts.

5. Start the engine and check for fuel leaks. On late models the "Check Engine Light'' will stay on after installation is completed. The memory code in the control unit must be erased. To erase the code disconnect the battery cable for 1 minute then reconnect. Refer to Section 4 if necessary.
