'85 300TD Shutoff problem
I think that I determined that the check valve in the main vacuum line was causing the issue. It was only pulling a few pounds of vacuum through that valve. The other vac connection pulled quite a bit better, so I took the lines off the check valve connection and joined them to the other connection. Car shuts off now, so the main issue is manageable for the moment. I will be ordering a new main vac line and then put stuff back like it was once I replace that.
I have a question regarding the fuel shut off valve however. There are three vac connections going into the switch. A brown line that goes to ign, a vac line that goes in the top, and then there is another short, 90-degree hose comin out of the side. This was not connected to anything (in my case) and I did not see any vacant lines that may have come disconnected from this. Is this some sort of breather line or something? or should it be connecting someplace? Thanks! |
Methinks you are confusing the Vacuum Control Valve (VCV) and the shut off valve. The shut off valve only has one brown line going to it and it is down in between the IP and oil filter housing. If you have a brown line going to the VCV something is misrouted. The line coming from the VCV not hooked to anything is a vent.

I do not know which line goes to which nipple but there is only 2 lines that connect to it. Both are Brown with the exception that one of the lines has is Brown with a stripe. If the Line positions are not proper the Valve will not function like it is supposed to. There is a Black Tube not connected to the shutoff that goes through the fire wall that connects to nothing and is a vent tube. |
