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 a mechanical fuel pump located on the engine. It is in the drivers side front below the distributor.
To remove the brake rotors from a 1989 Jeep Grand Wagoneer, first, lift the vehicle and secure it on jack stands. Remove the wheel, then take off the brake caliper by unbolting it and hanging it out of the way (do not let it hang by the brake line). Next, remove the caliper bracket, if applicable, and then take out the rotor, which may require removing any retaining screws or gently tapping it if it's stuck. Ensure you check the condition of the components and replace any worn parts during reassembly.
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.
