1969 H/O vacuum line routing
There are three ports behind the carb on the intake. The large one goes to the brake booster, which leaves two. On an air car, one goes to the vacuum bulb on the firewall and the flapper door motor T's off that. The other port goes to the air cleaner snorkel.
How does the routing change on a non-air car. Does the flapper door have its own dedicated port, or is one blocked off and it T's off of the air cleaner port.
