I recently had some problems with some rotted wiring going to my fuel pump on my 87 k5 silverado.Luckily i have a hatch under the rug above my tank inside the bed of my truck..There are 2 wires plus 1 power wire coming from dash and 3 wires coming from inside tank. 1 wire thats grounded to chassis and 2 others.I cant seems to get fuel gauge to work.Can anyone help me with some sort of wiring diagram or if anyone has any knowledge of how the wiring works. I got the fuel pump to work but not the fuel gauge.Any help will be greatly appreciated.
