my 77 Is at empty go to fill her up it only takes 2 1/2 gallons, So I know I have just a little after the E. And before I filled up I thought What crappy gas milage,
I would check your wiring under the seat on top of the sending unit, Mine wouldn't read with the 7 volt regulator, so I by passed it and run 12 volts to it, seems to work fine, I have an extra gauge just in case I fry this one, I did put a 7 volt reg, in for the temp gauge,
So I'm not sure how accurate these things are, It's not hard to get to the sending unit, just take off your seat, and and there it is, Theres just a little spin ring on top with the two wires, Just make sure your gas level is below that sender, Or that could get messy,
With the sending unit out, plug it in, and you'll have to ground it to the tank, Then you can move it up and down by hand, watch the gauge and see what it does,
Could be bad wiring, bad ground, or bad gauge, I'm not so sure about the 7 volt reg, set up.
Good luck
