How about the requirements for truck delivery of 100LL? I once
understand that there can be no other fuel on board the truck, and
that the tank(s) have to be flushed with 100 LL and the flushing
mixture thrown away (a hazardous waste?) before the airport load is
put in.

AFAIK, 100LL is not moved by pipeline anywhere. So it's trucked/railed
to either the final destination airport or a truck loading terminal.

I suspect the delivery truck from there may be dedicated to 100LL, but
maybe not.

I can't see the requirement before delivering 100LL; but after may be an
issue lead getting into autogas.
