I am searching for vacum source for a.c.and heat. According to the build manual the source is at the intake manifold. I have found this snorkle. Do I run the vacum hose from this straight to the panel? Should I run it to an acummulator vacum tank(round thing) and then to panel? My assembly manual doesn't show it or I can't find it.

there should be a fitting in the intake manifold behind the carb it should have multiple openings, the largest opening should be connected to a acummulator which looks like a small coffee can about 4 inches in dia. and about 4 inches long and mounts to the A/C box near the firewall there are 2 openings in the acummulator, one is the vac line in and one for the A/C vac. line to connect to QUOTE]Originally posted by jdd44:
