Had a similar problem in my "69" and one day while it read past full I ran out of gas about a mile from my house. Called my son and after putting in 5 gals. and cranking on it forever, got it started and drove it home. The next week dropped the tank and put a new sending unit in it , problem solved. I think 68-72 all used the same tank and sending unit . Year one,National parts depot, Original parts group, Ground up, and Eckler to name a few all carry sending units. Might also be able to get it through Advance auto,Autozone,NAPA, ect. Hope this helps, nothing feels dumber than sitting along the side of the road in a muscle car with no gas in the tank and having people that you know drive by and look!!!!!!

However, my fuel guage is not accurate. I put 5 gal. in the tank and it reads past full. If I have to drop the tank to check my grounds, should I just replace my sending unit. And if so what sending unit do I need for a 70ss 396. It looks like dropping the tank is going to be quite a ordeal. I think I am going to have to partially remove my exhaust. Thanks again yall for your help. Bob
