    The odds of 8 gauges going bad at the same time are near zero

    do the gauges have two wires ?

    a lot of the older trucks like the older cars had gauges that passed the electricity through the gauge and to the sender .
    The sender in the fuel tank or temp or whatever , then grounded that voltage by a variable amount , and the variable voltage is what causes the gauge needle to move .

    you need to find a wiring diagram
    Or just track down the power source for those 8 gauges

    it’s likely a bad fuse or bad relay or a bad connection .
