How do you change a fuel sending unit in a 1993 Explorer?

It is in the gas tank, so you will have to drop the tank. Wait until the tank is near empty as the gas wieghs a ton. You will need to get a manual that shows the correct procedure. It is a pain. I have used the odometer for quite a while so if you can do without, do without. www.explorer4x4.com has a lot of info for the Explorer in their forum section.
