If you are talking of the large lines to your Hydrovac, they are more like
1/2" or bigger. They go to a one-way valve mounted on firewall, Then to your
brake unit. Seems to me the line to the wiper comes off a second source on
my original intake. doubt a small line is good idea for brakes, should be OK
for the wipers.
