clogged fuel filter on 2002 Nissan Maxima 6 speed

How do you know the filter is clogged? 1 Relieve the fuel system pressure by first removing the fuel pump fuse. Then, start the engine and allow it to run until it stalls. Crank the engine for 2 to 3 seconds to release the fuel pressure. Turn the ignition off. 2 Disconnect the negative battery cable. Remove the rear seat bottom and the inspection hole cover. Disconnect the electrical and quick connectors and remove the six screws. Remove the fuel level sensor unit and the fuel pump assembly. Then, take out the flange and snap fit portion of the fuel pump. 3 Remove the fuel tank temperature sensor harness, the fuel level sensor flange, and the fuel pump connector. Disconnect the quick connectors from the fuel level sensor, and remove the fuel level sensor from the chamber. Take out the fuel filter. 4 Put the new fuel filter in the chamber, followed by the fuel level sensor. Attach the quick connectors to the fuel sensor. Connect the fuel pump connector and put the fuel level sensor flange and fuel tank temperature sensor harness back. 5 Place the fuel pump assembly inside the tank. Replace the screws and electrical connectors. Reattach the quick connectors. Reconnect the negative battery cable. 6 Start your Nissan Maxima and check for leaks, and make repairs if necessary. When repairs are complete, replace the inspection hole cover and the rear seat bottom.
