1985 camaro - after a long time, the fuel pump failed. Car towed and they replaced the fuel pump. I drive 2 miles to the gas station and remove the cap - excessive pressure is exiting the gas tank. I'm in Florida - I know it's hot here, but I've had this baby 31 years and never did this. The pressure will eventually go away after several hours of sitting in the garage, but what's causing the pressure build up? Did something happen when they dropped the tank? or when the fuel pump went bad? (1985 v6 2.8 base camaro).
