I'm going to take a breather for a while & regroup later. Unfortunately when I bought the car there was no gas tank/sending unit at all, so I bought both new thinking nothing could go wrong (what was I THINKING?). For now I'll keep track of how much gas I put in & synchronize that with my trip odometer and do the math @ 15 mpg (est) and ignore the gauge. If you see a Yellow '66 Barracuda with a black vinyl top stopped dead on the berm of I-75....at least wave as you go by. :)
