I just spoke with my installer, and he said it is an open system and shouldn't have the pressure when opening the gas cap. He said the vent tube installed by the factory would have to have a kink in it to cause that situation. He also said they had a similar problem in the Daytona coupes and had to drill a small (1/8") hole thru the filler that would allow the tank to vent. It wouldn't be a safety issue. Thoughts or experiences.
