Remove the back seat fold back the carpet and there is a round access panel with four screws. the fuel sending unit has a locking ring holding it into place. be sure to thoroughly clean the area before removing the fuel lines and the locking ring. you can purchase a tool to remove the locking ring @ www.grandwagoneers.com. or you can use a screw driver and hammer as I did. This is NOT the best way. you then need to lift up and angle the sending unit to remove. Be fore replacing be sure to test the unit. this way if there is still a problem you are removing the sending unit again. Good luck

it is mounted in the dash on the drivers side. It is designed to be see from out side the vehicle.
A few possibilities here. Oil and oil filter issues, fuel injector issues, cam issues.
It is located on the inside of the firewall, left of the steering column. It is way up and hard to see and get to, but it is there!
It is a mechanical fuel pump located on the engine. It is in the drivers side front below the distributor.

I bet this happens with less than half a tank. Your fuel sloshes back and forth and the float on the sending unit is moving and will drop this seems to be a common problem on replacement sending units.
I have not found a vin on the frame. There is one on the dash visible to the outside through the windshield and there is one under the hood on the drivers side on the firewall.
No

My owner's manual for my 1988 Grand Wagoneer has a diagram that shows the cigareete lighter fuse to be a 10 amp fuse located 1 tier up from the bottom of the fuse box on the left hand corner. It is apparently the same fuse as for the radio.
