I recently replaced the dash on my '82 coupe. Since the replacement my fuel and temp gauges have been running higher than before, and are somewhat erradic. On both of the '82 coupe's I've had the fuel gauge has gone only to the 3/4 mark when filled up. Now the gauge sits above the full line on fill up. Any ideas on what's going on here? Thanks!
