We build lots of street rods so deal with this with the install of aftermarket senders. What seems to work as good as any is to fill tank HALF full and adjust sender float arm so gauge reads 1/2 full. This gives a near equal error for both full and empty and so far hasn't led to rides sitting on the shoulder out of gas. A good idea is to zero the odometer and carry a gas can so one can get a firm idea as to when things get quiet. If you do it more than once then the one behind the steering wheel needs adjusted.
