Turbo Inlet hose fittings - charcoal can & frequency valve

[Ben Swann]

I was able to get the engine started and run the cam in, no drive to seat
the rings yet, and need to double check a few things and improve upon a
custom turbo intake line - between the airflow/fuel dist and the turbo
intake.

I needed to replace this hose assembly - the big metal tube and rubber U
hose which are in line to the turbo since the hybrid unit has a larger 2"
opening and I am adding a by pass valve.  I have constructed it with the
bypass valve fitting as close to the turbo inlet as possible attempting to
direct its flow that way as well.

There are two vacuem line fittings on the hose I am replacing, the one that
goes to the turbo intake on the '87 5000 turbo quattro with k26 stock
setup.  I believe they are 1) for the charcoal fuel recovery canister and
2) the other for the frequency valve.

I was wondering if I can just provide one fitting and tee off it? Or..

Alternatively, since I am not even using the frequency valve control in my
setup (schrapnel knob), though I may revert, can I leave the fitting off
all together, and plumb the recovery line into the manifold with a one way
(vacuem only) valve in line?  there is an unused fiting in the rear of the
intake manifold that would be perfect for this.  I could just leave the
frequency valve out of the pictur as it has been, unless there is another
place it can go - just putting these little fittings bothers me.

I do have a way to put a fitting in my custom air hose, but it is kind of
messy.
