Theres a connector on top of the fuel tank, seperate that and run a wire from the negative post on the battery to the pin thats connected to yellow/white stripe & turn the key to run-not start- fuel gauge should go to full. If it does the sending unit in the tank is shot. Not sure why, but Ford grounds everything (tail lights/fuel pump/sending unit under the dash. Seems they could just ground to the sheet metal in the back. But the ground from the negative battery post will do the trick. An "electrical & vacuum troubleshooting manual" is very handy to have for this sort of thing. 20 bucks from www.helminc.com

hey just a thought.. but if you dont figure out the wiring stuff... just use your odometer. I know tire size messes that up, but my gauge works fine and i still use the odo.. i got 31x10.5's. my odo thinks im going less distance than i am.. my bronco came with 29's. anyway i get around 70 miles (again my odo shows less distance than i really go because of the tire size) per quarter tank. That includes the fact that im 18 and im not exactly nice to is most of the time.

Yeah, like 'Hell Fish' said, the floater tank is usually the problem. If you remove the pump assembly and check the float, it should be empty. If it's full of gas, then that's your problem. Usually, the crack is very hard to see. I run a specialty salvage yard for Rangers, Explorers and Bronco IIs, and that is a very problematic part.
