Fuel gauge
hello I have a 1988 f150 5.0 2 wheel drive I have an issue with my fuel gauge I currently been struggling so here’s my issue
front tank works but the needle marks passed full..
rear tank don’t work whatsoever even if I change the fuel selector switch it will still suck up fuel from the front tank
i been having the issue with my fuel gauge I grabbed an after market fuel gauge and wired it up still didn’t work I am lost I kinda need help

The rear sender uses a Yellow/Light Blue wires for the signal back to the dash gauge. The Black wire is ground for everything related to the tank pumps and sending units. The EVTM diagram above is for a 1991, I also had a link for a 1988 fuel system. Ford is well known to change color coding from year to year occasionally, perhaps your '87 is unique.
I am a little fuzzy on what you are trying to accomplish. Are you re-installing a rear tank or planning to run on the front only?
