Vacuum line elimination help
I have an 84 4runner, and I'm in the process of swapping the carb and intake manifold. The vacuum lines are a mess of a rats nest to say the least. I searched around a bit but couldn't find the info I'm looking for.
I'm trying to determine which vacuum lines I can get rid of. The truck is emissions exempt and I'm blocking off the EGR. I'm installing the Offenhauser C intake with the standard Weber carb. I'd like to get rid of whatever isn't necessary. The shop manual I have doesn't have a good diagram, and the hood has been replaced prior to me buying the truck, so I don't have the diagram.
Does anyone have a pic of the vacuum setup with the lines labeled and traced or a good diagram? Also, if anyone knows which lines I can get rid of, your assistance would be greatly appreciated. I'm trying to trace them all, but I don't have a great deal of experience in this area and feel like I'm getting in a little over my head. Thanks for any help, guys!

i only use 4 lines total.
1) from distibutor to vaccum advance
2) from distributor to carburetor
the next two arent vuccum lines but hoses and both are on the top of the vavle cover.
1) goes from the rear outlet w/ pcv vale. below the carburetor to the 1/4 inch inlet on the multi inlet vaccum post on the intake. This should have run to the airbox on a stock carb.
2) Goes from the front outlet to the spot on the air breather.
