Need Help Verifing Quadrajet Vacuum Lines / Ports
I have a 1969 K10 with 350 V8 w/Quadrajet carburetor, 4 speed manual, PS and PB. Truck was built in Janesville. The stampings on the carburetor body are: 7045583 YZ 1276. I believe the carburetor decodes as follows: 4MV, 1975, California only.
I can’t find a vacuum diagram for the truck. And even if I did, because the carburetor is not original to the truck I couldn’t determine if everything is hooked up correctly.
So, I need help determining what all of the vacuum lines are for and that they are connected to the correct ports. I have included several photographs that have the lines / ports numbered.
#1a / 1b: Distributor vacuum advance line. Is 1b connected to the correct port? Should it be connected to a ported or direct vacuum source?
#2: ?
#3a / 3b: ?
#4: ?
#5a / 5b: PCV line. Is 5b connected to the correct port?
#6: ?
#7: Brake booster vacuum line. Is 7 connected to the correct port?
Thank you in advance.
