I have a 71 with a 350 in it. After i got her going i noticed that the gas gauge isn't working. i know the tank was replaced before it was parked but he said he thought it was working. Any opinions on where i should start trouble shooting?
check the ground, then check with a ohm meter to see if the gas gauge actually works, you might have to pull the sending unit out to do that. Is the wire actually on the gauge and not fallen or corroded away from it?If everything checks out at the tank, check that the wire hasn't been broken from the gauge to the sending unit. If that all checks out, it could be a faulty gauge. Try swapping it out with another one.
