I am not sure what this is.
I have a small grey hollow line (1/8 inch) and a small black hollow line (1/8 inch) coming out of the firewall just to the left of the wiper motor.
The grey line has been chewed off and I don't know where the end of it is.
The black line is still there and looks like it connects into the top of the engine just behind the carb.
These two lines come out of a round connector that is in the firewall.
There seem to be three 'connections' at the back/topside/center...
What is it? Dual Vacuum Solenoid?
