I believe the 02 has the sending unit installed in the back of the tank, making replacement a simple DIY. With the tank about 1/4 full you can remove the old sender and replace it.

How do you know when the tank is 1/4 if the gauge doesn't work? Good question.

 

I don't know but once it get 3/4 I full it again i work this way couple days now .

the fuel sending unit is inside the tank in the right side time to change it?

 

If you remove the boot liner, exposing the tank, I think you will see the sending unit below the midpoint on the back wall of the tank. I have attempted to attach a diagram.
