That's what I thought but was making sure. I think the line that is broken goes somewhere on the engine. I have the three lines coming from the engine to the lines above they feed to different places with one going to the reservoir. The top line that was broken off I have capped off right now. The one line coming from the reservoir is going to the check valve and then thru the firewall. I am wondering that when it broke before if they added a new y-port to feed all three hoses into the lower part of the reservoir? And never removed the broken part from the top port on the vacuum reservoir. Thanks for the information it is helping me to narrow down possible places for that hose to go.

Good old Bill

My 4.2L V-6 vacuum line comes from engine to the check valve, then it tee's to the firewall line and down to the reservoir. The reservoir and the cabin circuits are on the opposite side of the check valve as the engine is. Thus vacuum is maintained in the reservoir and cabin circuits when engine is shut off.
