Precisely, Sir!
You'll want a 5449K132 for a "T".

Hold on, I may have an old write-up. OK, here it is:
=============
Parts ordered from www.summitracing.com :

1. VDO-150206 boost gauge for $31.69 (52mm DIA, -30"Hg to +25psi
boost, white face/red pointer and IMO matches the OEM UrS gauges much
better than the Autometer gauges. It can also have red illumination
if you ask for the red Si bulb "condom")

2. ATM-20191 single gauge pod for $19.95 (actually this is the Audi
A4 part but it fits almost perfectly).

For plumbing of the above I used the Audi OEM 5mm green nylon tubing at
the ECU and later reduced it to the American aftermarket 1/8" nylon
tubing for the boost gauge and the boost controller.

Parts ordered from www.mcmaster.com :

3. 5779K123 - 1/8" tube OD x 1/8" NPT (this one goes onto the boost gauge).
4. 5449K132 - "T", 5mm x 5mm x 5mm tube OD (this one cuts into the Audi
OEM 5mm green nylon tubing at the ECU).
5. 5449K173 - 5mm tube OD x 1/8" BSPT (male).
6. 5779K123 - 1/8" tube OD x 1/8" NPT (female)
The 3b and 3c together form a 5mm x 1/8" OD tube reducer. Note that the
NPT standard is tapered and is 27 threads per inch, whereas BSPT is
straight and is 28 threads per inch. No sweat, just use some Teflon tape.

Optional parts:

7. 5111K171 - "T", 1/8"x1/8"x1/8" tube OD.
(I used it after the reducer but before the boost gauge to "T" off the
boost to the boost controller).
8. 51025K251 - Plastic plug, 1/8"
9. 5449K332 - Plastic plug, 5mm
The last two items allow you to plug the unused openings in the "T" if
there is a need to reconfigure the sys.
==============

Folks, please doublecheck the part numbers. Some of them may be NLA.
Also keep in mind that back then I ran the Turbonetics Boost Controller,
thus I needed a second outlet in the 1/8" tube size. You may approach it
differently. For example, you can run the 5mm tube to the gauge instead.
   Will be clumsy, tho.
