I have a 1969 Cutlass S and the fuel gauge is reading this when I start it up.......Any help would be greatly appreciated.

Because the connection between the gauge and the sender has been broken.

Welcome to Classic Olds.

If you search the forum, you will find that this question has been answered a number of times before.
A quick glance shows information here, here, and here.

You need to check to be sure that the sender wire is connected to the back of the gauge, then check to be sure the wire's not broken as it passes from the back to the front, then check that it is connected to the sender, and that the sender is properly grounded.

My 70 was the same way. I was told it was most likely that the sending unit was bad. Bought one off evilbay, installed it and now i know how much gas i have.
