My vacuum system is a mess. The apparent vacuum source connection right below the carb has three connections. From what I can tell, one goes to the vacuum reservoir, one goes to the distributer area, but where does the third one go? Currently it goes through the firewall because the reservoir is bypassed. I think the reservoir goes through the fire wall instead.

Any help would be greatly appreciated.

 

Your best bet is going to be to get a schmatic and start tracing everything. There's a couple sources online.

One is Vacuum Schmatic

Good Luck.

 

Thans for the help. I will check it out.

 

is it an automatic

 

It is a 3 spd manual with A/C

 

yeah i would say you have alot of looking up to do...did you follow the line through the firewall to see where it ends

 

haven't traced it but the vague diagram I found online shows two going through the firewall. One from the heater control valve and the other from the vacuum canister. I assume it is directly connected since both of those are bypassed. I probably attaches to an actuator motor I assume and none of those are working, lol. Does a vacuum system have to make a complete loop like electric circuits?
