This is a tough job and not easy task, If I had to do it again, I would pay someone to do it, again if you save big buck on labors this will be the way to go. there are 2 electric fuel pumps( 1 is external) on some bronco II(89 v-6 2.9). one is in the tank and the other is located on the chassis on the driver side, near the front fender on the inside area of the chassis. Longer answer, with opinion
I would suggest extreme caution whenever messing with fuel tanks, and never do this indoors. The risk of explosion is high when you open a fuel tank. 1989 and up only have a single fuel pump, in the tank. You have to remove the tank, and rotate the lock ring on the fuel pump port, lift out the pump assembly. Easily said, much harder done (I procrastinated a year before doing it). First, if it died, you may have a fair amount of gas in the tank which needs to be removed, otherwise the weight is unmanageable and increases the risk of a spill. Best to remove as much gas as possible. If you have the Eddie Bauer model, you also have to remove the skid shield (2 bolts each, front and back); the rear ones can be nasty, as they're tucked under the bumper (mine was smashed in). The biggest pain is getting the hoses and wiring off the tank before dropping it; there isn't enough slack, and not much room to reach in. If you've never dealt with newer high pressure fuel lines before, you may need to acquire the tool set for those. Filler hose is disconnected at the tank neck end, then the tank is partially lowered by loosening the straps. Fuel lines (out and return) disconnected, pump/sensor cable unplugged, vent hose disconnected, then tank removal continued. good luck!

Did you check to make sur you have voltage at the sensor? Before you changed out the sensor did you run a wire from one post to the other post on the connector?
doing this will make your gas gauge go to full,unless the gauge is defective
