The post the other day about a PCV valve for a Scout 800 made me take a closer look at what I have on my 68' 800, w/226 motor and 4 speed. Here is what I have. I have a line (vacuum?) that runs from the fuel pump to the top, rear of the intake manifold. There it goes into an elbow. One end of the elbow is plugged, the other end is tied into the intake. Just above the intake on the elbow, a small (approximately 3/8" O.D.) tube comes off that and that is plugged. To complicate matters, I have a small line on the side of the carb that is plugged too. They look like they should be connected. One more thing. I also have a road draft tube. No PCV valve, no opening in my valve covers. Any insight as to the two plugged tubes? Motor runs fantastic.
