Yeah, the Meter Match will fix this. After installing it, you calibrate four points on your fuel gauge: Empty, 1/4, 3/4 and full. You have to do a bit of math beforehand, starting with how much fuel does an empty tank in your car actually take. I did this by running my car out of fuel - completely dry. I then filled it all the way to the top of the filler neck. My stock 1974 Duster with a new repro 16 gallon tank took 15.1 gallons of gas. So you now know (and calibrate) the empty and full points. You just have to run drive the car until it burns one quarter of its fuel, based on your known observed gas mileage. You stop and calibrate the gage at this point. You then do the same for the 1/4 point. Trust me, it'll work. It's not as hard as it sounds.
