We're contemplating just having long enough tubing so that we can put it into the transport configuration without the need of the butterfly valve which likes to leak.

I would say this is illegal as the rules are written, per the allowed parts list and the rules about the dump valve.

Instead, use a standard shop compressor quick connect fitting. It's a standard fitting, so it's a legal part, and when disconnected does not leak any air.
