another Fuel pump or wire problem
I had this posted in the superduty page and was told I should post it here instead. I got one responce saying the guage should work even if the pump isn't working.
I just bought a 96 F250 flat bed with dual tanks and 213,000 miles. I have not driven the truck yet except home from the dealer. My rear pump seems to be not working. No sound when I turn on the key with switch in rear position and it won't start or dies if I switch to rear tank. If just the rear pump is gone, would the guage read the fuel level of the rear tank when selected? Or with the pump not working the guage won't work either for that tank. If it should work, I might have a wireing problem. I filled the rear tank before I knew the pump was not working because the front tank leaked out the filler tube when I tried to put fuel in. The filler tube was bent over the frame causing the gas not to go in the tank and back-up out. I bent it straght but have not tested it yet. So I have a full rear tank with a nonworking pump and nearly empty midship tank. The guage doesn't change at all when I switch tanks. Metal tanks. I seem to have other wire problems with the rear signal and break lights both on the truck and when I hook up my trailer. I have not started to chase that problem down yet.

All of the wires for the lamps on the back of the truck, fuel pumps and gauges all go through the same wiring loom and its main plug (C205) and it plugs into the front of the firewall.
Here is a link to a diagram of your fuel system.

I just sold a 1987 F-150 with dual tanks (Metal) I did not have any problems with the fuel tanks with the exception that both tanks would register full untill there was only about 2 gal. of gas left in the tank. for that reason I always keep one tank full at all times.
