Vacuum Line Size?

[rboltz]

What is the tubing size, (1/4,5/16) etc., of the vacuum lines such as those to and from the vacuum side of the fuel/vacuum pump? All my lines were removed, so I have no reference, and now that I have a dual pump I want to pipe it up to the wipers, etc.

Most of the metal lines the vacuum lines go on are 1/4 inch EXCEPT:

The line from the front part of the head, the block on the drivers side where 3 metal lines connect for engine vacuum, to the vacuum pump port labeled manifold, the port away from the valve cover on top, is 5/16ths
The line from the ignitor housing to the block on the front part of the head vacuum port is 7/32ths


The lines rubber hoses generally connect to metal lines that screw into the fuel pump/vacuum pump, ignitor...etc...are you missing those metal lines as well?

I only have the line from the manifold, behind the thermostat, to a "T", then to the wipers and the civy distributor. All the rest were cut and/or removed.
