Nissan 25060-ZQ60A Fuel Gauge Sender Unit

Unplug the battery cable from the terminal that's negative. Relieve the fuel system pressure. In Armada models, you need to take out the second-row left seat, the second-row center seat or remove the center console and low part beneath it, before removing the third-row seats. Pull off the seat belts connecting the second and third rows to their flooring. Take out the trim on the left (8-pillars), the part behind the left row-two seat using the trim panel on the rear, and pull out the door sill plate on the left side. Take off the floor carpeting to see where the inspection hole cover is hiding. You must turn both retainers counterclockwise by one quarter to pull off the inspection hole cover. Take off both the fuel pump's electrical connection and lines. Keep track of where the fuel pump module is sitting by the fuel tank, and use large water pump pliers to turn the module's lock ring counterclockwise to release it easily. Take out the fuel pump module from the tank, moving it around as needed to keep the float arm for the fuel level sensor safe. Sometimes you need to disconnect the fuel level sensor from the pump module before removing it. Check the condition of the fuel pump/fuel level sensor O-ring, and put in a new one if needed. When you move a fuel level sensor to another fuel pump module, follow the sensor harness to its wire end and pull it off. Grasp the locking clips on each side of the sensor with pliers, push down to open them, and move the sensor straight up out of the pump. When pressing the sensor into place, check that the locks go in without forcing. Installation is the reverse of removal.

Take the cable away from the negative terminal of the battery. Relieve the fuel system pressure. With Titan models, you can't see or inspect the fuel pump like other models; you must remove the fuel tank. Pull out the fuel pump links, and detach the electrical cord from it. Make a note where the fuel pump module sits in relation to the tank before you loosen the lock ring holding it in place. A special tool from auto parts shops will loosen the lock ring, but large pliers work as an alternative. Gently take the fuel pump module out of the tank, turning it at an angle so you don't damage the arm that controls the fuel level sensor float. In certain cases, you need to disconnect the fuel level sensor from the pump module before taking it off. Look at the fuel pump and fuel level sensor O-ring, replace it when you see damage. To move a fuel level sensor to a new fuel pump module, follow the sensor wires until they meet its electrical plug and remove it. Separating the sensor from its pump section involves using needle-nose pliers to push down on the lock buttons on both sides and gently easing the sensor upwards. Snap the locks of the sensor module into their proper places during installation. Installation is the reverse of removal.
