RE: 'S-tube'? No such thing, for '67 390. I think you mean a PCV tube... By Barry B - 01/19/2005 3:08:34 PM; IP 64.162.186.125 Here's the only pic I have of a '67 390GT intake with the tube attached. The front end screws into the fitting on the intake and the rear end uses a short piece of hose to connect to the other fitting. The end of the long hose attached goes to a right-angle fitting in which the PVC valve is screwed into. The PVC then inserts into the valve cover grommet. The Ford technical stuff I have read refers to this as a balance tube. They say by connecting the two intake runners the PVC gets a better signal and if the PVC were to be connected to only one of the ports, there would be excessive pulsing at the valve (plus I think it would lean out that runner).
