Hi. Looking to find out what aftermarket fuel gauges will work on this truck. I ended up replacing the fuel tank last year because the original sending unit was not working. A buddy of mine had a tank with a working sending unit in it, so I just switched tanks. Now, when I hook the sending unit up to the original gauge, it will not read correctly. It always reads about 1/8 away below Empty, no matter how much fuel is in the tank. It was off the exact same truck, the only difference was a year or two in age between both trucks.
Before I received this truck last year, my grandfather (original owner) had a guy install a UAP aftermarket fuel gauge. This gauge was also not working, however, it would read between 3/4 and full all the time. I'm wondering if the UAP gauge is not compatible with the sending unit (I read something on the internet about the gauge having to have the same resistance specs as the original, not sure if this is true or not). I've replaced both wires from the sending unit up to the firewall and I know the sending unit works on the new tank because we checked it before the tank was removed.
Any info is appreciated. Sharky
