Nissan 25060-1KM1B Fuel Tank Sending Unit

To remove the Fuel Level Sensor, first depressurise the fuel system and disconnect the battery negative terminal. Lift out the rear seat cushion for access, then turn the three retaining tabs 90 degrees to lift off the access cover, exposing the fuel pump and Fuel Level Sensor. Brush away any dust or dirt around the Fuel Level Sensor to prevent it from falling into the fuel tank during removal. Disconnect the wiring connector from the top of the Fuel Level Sensor and depress the coloured tabs of the quick-release fitting to disconnect the fuel hose, covering the hose union and fitting to prevent dirt ingress. Twist the locking ring from the top of the fuel tank and carefully lift the Fuel Level Sensor out, avoiding damage or fuel spillage. Remove and discard the sealing ring from the top of the fuel tank, as a new one will be needed for refitting. Position the new locking ring with the arrow mark pointing toward the rear of the vehicle and temporarily screw it back into place, tightening securely. Depress the legs of the Fuel Level Sensor locking tabs and slide the Fuel Level Sensor from the fuel pump body, releasing the wiring from the guide at the top of the pump. Use a screwdriver to ease the Fuel Level Sensor wiring end fittings off the connectors at the top of the pump, then remove the Fuel Level Sensor. For refitting, reverse the removal steps, ensuring to fit a new sealing ring to the top of the fuel tank, insert the fuel pump into the tank while engaging the tab with the cut-out, and keep the pump pressed down until the locking ring is fitted and tightened. Position the locking ring with the arrow mark pointing toward the rear and securely tighten it. Finally, ensure the fuel hose and wiring connector are reconnected to the Fuel Level Sensor, reconnect the battery, start the engine, and check for any fuel leaks before replacing the access cover.

The steps which have to be followed in order to remove and refit the fuel pump and Fuel Level Sensor on a Type 2 engine are as follows; First turn the fuel tank filler cap anti-clockwise to release any pressure that may be remaining in the fuel pipes as well as turn off the battery. To get to the Fuel Level Sensor, remove the rear seat and flip the three clips of the access cover in a horizontal position to remove it. Before conducting any operations on the Fuel Level Sensor, it is necessary to eliminate any contamination around it, especially dust and dirt. Pull the connector's wiring off the Fuel Level Sensor, and release the colored tabs of the quick-release fittings on both sides to remove the fuel hoses; these ends should then be shielded from dust. Tilt the locking ring from the top of the fuel tank and lift out the pump/Fuel Level Sensor being careful not to damage the sensor or fuel leak. If the fuel tank did not come with a built-in retaining clip, then this element has to be removed and discarded, because the new sealing ring will have to be inserted. Before refitting, the new sealing ring should be fitted to the top of the tank; the fuel pump should be inserted and the tab on the pump should then engage with the cut-out on the tank or the lines should then be aligned, if there are no tabs. The pump has to remain pressed down onto the sealing ring until the locking ring can be fitted and adequately tightened, with the arrow mark online facing towards the rear of the vehicle. Last, join the fuel hose and wiring connector back to the Fuel Level Sensor, join the battery terminals and check with fuel leakage after the engine is started.
