Jacksoni, page 45, 3.I and 3.I.1 lists the fuel system and fuel shut off req's. As I read the rules, car fuel lines have to be separate from the driver's compartment so do not require fire sleeve or other fire protection (bike rules say any un-valved line has to be fire protected as they are usually really really close the rider where leaks are a bad thing). As for vents and/or vent lines off the carb, I would route them to a small catch can equal to the volume of the bowl(s) and fuel line from the shut off even thought not specifically called out in the rules.
Here is an older picture of the right side of the bike. remote petcock at the tank, fuel line down to a lower pressure facet/purolator fuel pump feeding a puck style regulator. From there it dead heads at the carb. My best friend is sponsored by Gates so I have access to fire sleeve. The carb vents to the atmosphere in two places, only one has a hose and it's not sleeved.
