One question how hard it is to drop the fuel tank and replace the fuel sensor in the fuel tank it is a 2005 Nissan Pathfinder 4.0L 4-wheel drive please help out if you can thanks

Answer 1

It's complicated. Here are the instructions from the service manual:

1. Remove the fuel filler cap to release the pressure from inside the fuel tank.

2. Remove the LH rear wheel and tire. 

3. Check the fuel level on level gauge. If the fuel gauge indicates more than the level as shown (full or almost full), drain the fuel from the fuel tank until the fuel gauge indicates the level as shown, or less.

NOTE:

Fuel will be spilled when removing the fuel level sensor, fuel filter, and fuel pump assembly for the fuel level is above the fuel level sensor, fuel filter, and fuel pump assembly fuel tank opening.  As a guide, the fuel level reaches the fuel gauge position as shown, or less, when approximately 15 (4 US gal, 3 1/4 Imp

gal) of fuel are drained from the fuel tank.  If the fuel pump does not operate, use the following procedure to drain the fuel to the specified level. 

a. Insert a suitable hose of less than 15 mm (0.59 in) diameter into the fuel filler pipe through the fuel filler opening to drain the fuel from fuel filler pipe.

b. Remove the fuel filler pipe shield.

c. Disconnect the fuel filler hose from the fuel filler pipe.

d. Insert a suitable hose into the fuel tank through the fuel filler hose to drain the fuel from the fuel tank.

4. Release the fuel pressure from the fuel lines. 

 

5. Disconnect the battery negative terminal.

 

6. Disconnect the lower fuel filler hose from the fuel tank, the EVAP hose, and the vent pipe quick connector. Disconnect the fuel feed hose from the molded clip in the side of the fuel tank. Disconnect the quick connector as follows:

Hold the sides of the connector, push in the tabs and pull out the tube. If the connector and the tube are stuck together, push and pull several times until they start to move. Then disconnect them by pulling.

 

7. Remove the four bolts and remove the fuel tank shield.

 

8. Remove the propeller shaft. 

 

9. Support the fuel tank using a suitable lift jack.

 

10. Remove the three fuel tank strap bolts while supporting the fuel tank with a suitable lift jack.

 

11. Remove the fuel tank straps and slowly lower the fuel tank to access the top of the fuel level sensor, fuel filter and fuel pump assembly.
