Nissan 17040-ZV60B Electric In Tank Fuel Pump

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.

The installation process involves reversing the removal steps. Ensure that the fuel pump module is properly aligned, and the lock ring is securely tightened. If the O-ring was replaced, make sure it's properly seated. Finally, reverse the steps to reassemble any components that were removed to access the fuel pump inspection hole.
