Im kinda in the same situation... I have a fuel cell with a sender, but Im sure its a GM 90ohm sender (well thats what I ordered anyway) but I havnt got it to work yet. I replaced the entire wiring harness in the truck, I put one of the wires front the sender labled as "G" to ground. Then the other connection labled as "S" to my gas feed wire on my cluster, then the other wire labled as gas gauge on my cluster plug to 12+ volts. The gauge buried to the 5 o'clock area of the gauge. I only have 5 gallons of fuel in my fuel cell..... So Im thinking I must have got the wires on the cluster plug for the gas gauge reveresed. My notes my be bad, Im gonna try to swap the wires at the cluster plug and see what happens....
