It is a proportioning valve, there should be one on the M/cyl and one
in-line, right below the brake booster. If you are using the stock
proportioning valve, the boxy piece of metal below the booster with the
rear brake lines running to it.

Is it a new or rebuilt? Where did you buy it?

You can get the metric double flared lengths of steel line with a
coupling on each end at any import part place. You could just replace the
whole length, doesn't that go from the M/cyl down to the proportioning
block?
Just measure how long you need it and buy the appropriate lines and then
just run the newly bent lines in between the M/cyl and the proportioning
block. 
You might want to replace the front lines while you are at it.
I would try to use the stock '81 Scirocco proportioning valve, because
I've had the cylindrical in-line 16V Scirocco proportiong valves leak and
it seems to common. 

On my RIP '81 Scirocco S, I ran 16V brakes with a new stock '81 M/cyl,
'81 proportioning block, and it was a great setup, a bigger M/cyl would
be even better.
