I would recommend sticking with 6mm for tapping into the lines. I made a few mods and started with the brass fittings thinking they would be better or leak less. Eventually, I went to quick-connect fittings because I had to troubleshoot a few lines, and the brass are one-time only fittings. Only buy good quality fittings rated to 250lbs or more. I had a helluva time finding 6mm fittings anywhere, but they can be found at Fastenal locations. Some had to special ordered, but they were there in a couple of days. They only use sell high quality fittings. For what you want to do, you will need a three way connector (2 at 6mm and the T with whatever you think may work) They have connectors with an 1/8" threaded fitting coming off the end. If you goto http://www.fastenal.com, type in "6mm" in the pneumatics/hydraulics section, you will see all the fittings they offer. If you need extra 6mm line, you can get that from them as well. All the pressure gauges will be standard fittings.
For example, here is a T dual 6mm fitting with a 1/4 male fitting: http://www.fastenal.com/web/products/de ... 441&ucst=t
You could then fit a female - schrader connection or pressure gauge to it.
Let us know how it goes. Good luck.
