Only way to know for sure is to wait for the gauge to hit bottom, and fill up, watching how many gallons it takes to fill it up. On my '67, the gas gauge reads about 3/4 no matter how much petrol I try to squeeze into the 25 gallon tank after the pump clicks off. So, I let it run down to the point where the "Check Gauges" light was on constantly, not just flickering, and the gauge was just a hair above the 'E'. It took 18 point something gallons, again, squeezing as much as I could into the tank. Nonetheless, its somewhat disconcerting to watch that needle plummet, and even more disconcerting to drive a 5000 pound very-hard-to-push mobile with the fuel gauge reading "Help Me!" ===== --Mike Pittinaro Piles of pitted chrome Hubcaps along the floorboard My junkyard-bedroom __________________________________________________ Do You Yahoo!?
