What is the pH of gasoline? Many additives, different gas blends in the country. What IS on the inside of a gas fill tube? Anything?

We currently use galvanized pipe and paint it with a cathodic electrocoat. The inner surface is not completely coated in electrocoat due to the reduced throwing power of the process but field performance using zero alcohol containing fuels is exceptional. Some car companies use zinc plated fuel filler tubes both inside and out. Coating the inner surface is achieved by placing electrodes inside the tube during the plating process to assist throwing power.
