My 2 cents on this issue comes from doing it more than once. 

I recommend removing the turbo intake tube (easy), the
throttle body (10 min.), and checking all tubes, etc. out as
you replace the breather hose. (This dis-assembly also makes
distributor & plug wire work a piece of cake.) There is so
much mucking around in back of the engine to get this job
done right, with the added thrill of possibly damaging one
of the vacuum hoses, that opening the area up really pays
off. Don't forget to fish out the flash arrestor (a coiled
wire) from the aft end of the old breather hose, and
re-install it in the new one.

This will also expose the valve that the breather hose leads
to. You will probably find the 3/4" hose leading from the
valve to the connecting tube rotted out as well. This is
also a good time to replace the highly perishable vacuum
line going to the bypass valve with a 3/16" copper tube. 

Before re-assembly, clean the throttle plate well. A major
stalling cause is a dirty throttle plate, which seldom gets
cleaned by the shops.
