Mine show full at the right side dot, but I can’t say if the sending unit is calibrated. When I approach the left dot, it’s time to get gas.

If you short across the two terminals on the sending unit, that should give you a full empty reading on your gauge, then you will know where the full empty reading is.

Edit: corrected info as pointed out by Bill Hanlon.
