Where to find 4kq brake parts?

[Kevin Hoff]

Greetings,

I'm returning to the q-list after a long hiatus; was here way back in the
mid 90's with a charcoal '87 4kq then went on to various VW's and Subarus.
Now I've gone and bought a beater blue '86 4000 CS quattro that has spent
way too much time in the salt.

I'm looking for the T-junction that tees off the single rear brake line just
above the fuel accumulator.  The one that's on there now just doesn't want
to come apart.
