stangman68 95 Report post Posted November 18, 2013 1969 SCJ, 4 Speed, Shaker, with tilt. I have a couple questions on vacuum routing. On the shaker base there is an orange vacuum hose attached to a small valve in the base of the air cleaner. Where does it connect to? Any vaccum port on the intake?? Also, one of the carburator studs, (back LH), is a vacuum stud. What connects to it? Is there a vacuum diagram out there for Big Block vacuum line routing?? thanks for any assistance.

rockhouse66 22 Report post Posted November 19, 2013 The diagram is in the shop manual. That orange hose on the bottom of the air cleaner base is a choke bleed and is supposed to go to a T in the choke tube that screws into the carburetor. Very unusual you still have the orange hose, and a very good chance that the choke tube with the T is missing. BTW, this T and extra hose/check valve appeared on '69 cars built sometime after about mid-Feb. and wasn't on the earlier cars. Quote Share this post Link to post Share on other sites
