I have a '88 F-150, with 5.0 EFI. The problem I am having is both gauges on the tanks are not working. The front tank gauge reads empty and the rear gauge pegs past the full mark. I know this normally means one is shorted out and the other is open, but could there be any other reason?? It seems to me I ran across this once before, but cannot remember what the cause was then......too many long nights
Any help is welcome.
Thanks,
LB
