Ok. you guys probably think i'm slow. But I just want to be sure. Be patient.
In the pic there are three arrows. The hose below the master cylinder to the left is what the blue arrow is pointing at. Thats what I am assuming is the vacum hose I am to use for the Top Engine Cleaner.
Now for the question. In which direction is the suction supposed to be coming from. When I removed that hose I didnt feel any suciton where it is connected to the firewall. But I did feel a very very small suction from the little black thing that is connected to that hose. The thing the yellow arrow is pointing at.
So do I let it suck in the direction the green or red arrow is pointing.
