Let's assume that a 1/2" fuel line will be maxed out, flowing as much fuel as
it can. What size hole/tube is needed for an air vent on the tank so that the
flow of fuel will not be slowed by pulling a vacuum? I'm just guessing that
air flows a helluvah lot easier/faster than fuel, and that something like a
1/8" or 1/4" vent will compensate for the liquid flow through the 1/2" fuel
line.
