Had a 63 Plus 4 fill the tank at a Shell Station in Key West last year, and several of the nozzles at the pumps were wrapped in plastic, indicating that they weren't working. Turned out the tanks were empty and the one that wasn't wrapped in plastic was a tank that was full of water.
The car filled up using the one that wasn't wrapped in plastic and went some 100 yards before gasping to a stop. Took us a long time to figure out just what the the problem was. (We finally removed the carb bowls and found water not gasoline.)
We ended up having to drain the entire fuel tank, and refill with good gasoline. Car ran great after that. We learned to never fill up where there are plastic wrappers over some of the pumps. May not be a problem but why take the chance.
Cheers,
