Air Cleaner hose clips and connections?
 
2 Attachment(s)
Original air cleaner has a hose connector on top on the diaphragm at the front of the air cleaner which the stove pipe that comes up from the driver exhaust manifold connects to. Under the air cleaner are two ports and a hose holder. Nothing connected, but what is supposed to be here and where does it route and connect? Here are some pics. What hoses should be in place, how should they rout, where should they connect.

Do you have a factory Chassis Service Manual or Overhaul Manual for the truck. It should show what you need in one of those.

If you don't have them they are on line for download by board member "Hatzie".

I am going to move this to the 67-72 Chevy Trucks message board.

Yes, but it doesn't specifically show all I need to see. It doesn't say or show how the hoses route the type of hose (basic vacuum and size or ribbed) or specifically where they connect nor does it show if there are clamps involved and what type if so. I need to see an actual real life correct setup to get it right.

Perfect! Where exactly does the hose connect to manifold vacuum? Reason I ask is there is a port on the side of my carburetor that is capped and currently unused.

Note the white stripe vacuum hose going to the carb. The port that hose connects to is on the passengers side of the carb in the middle of the choke linkage.
