Thanks, I was focusing in on "18 T" which is the Feed Wire " tto the fuel sending unit... Anyone... the connection of 1969 Camaro fuel sending unit to car...is it 18T ? Tan wire ???

if memory serves me correctly GM fuel gauges of that period had a round pin about 1/2 high that the sleeve on end of wire coming through the floor plugged on to.. some of then also had a flat clip for grounding.
