Where is the Fuel pump and sender located?

Hello,

Does the gas gauge show empty when ignition is off?

The in-tank fuel pump is accessible from under the rear bench seat.

1.
Release the residual pressure in fuel line.
2.
Turn the ignition switch OFF and disconnect the negative (-) battery cable.
3.
Remove the rear seat.
4.
Remove the fuel pump service cover (A). See image 1
5.
Disconnect the fuel pump connector (A). See image 2
6.
Disconnect the fuel feed tube quick connector (B). see image 2
7.
Remove the plate cover (C) by using the special service tool [SST No.: 09310-3P100 or 09310-2S100], see image 3. A large head flat screwdriver can also be used to knock the retainer loose. Remove the fuel pump from the fuel tank. see image 4

Assemble in reverse order.
