79 gs850 haveing trouble with vacuum lines

[Anonymous]

I'm having trouble with a 79 gs850. I can't figure out the vacuum line for the petcock ,the small nipple.
There were no vacuum lines or gas lines hooked up when I got the bike. Is the gas the middle T that is attached and swivels at the bottom of the middle carbs?

The vacuum line for the petcock hooks to the #3 carb The fuel line from the petcock hooks to the fitting between the 2 & 3 carb The vent/overflow lines between the 1&2 and the 3&4 carbs are routed down to the rear by the swing arm and do not connect to anything

The fuel goes to the fitting between the 2 & 3 carb from there it feeds all of the carbs thru interconnecting tubes.
If you look at the carbs from the rear Carb # 2,3,4 have a fitting on the side of the carbs The #3 is connected to the vacuum connection on the petcock The fitting between 1&2 on the #2 carb and the connection between 3&4 on the #4 carb are the vents
