I'm completely confused at a few things for installing my boost gauge.

My gauge came with reeeaaaaaly small diameter vacuum line. So small that the entire line fits inside the hole on a 3/16th fitting[ not around the barbs, but inside it! ] . Its the white/clearish vacuum line that came with my faze boost gauge.

I'm not sure what kind of T fitting to use, because i need the T fitting to have a side small enough for my small boost gauge vacuum line, and then the other two sides would need to be big enough to fit the fuel pressure selunoid line...which leads me to my next question

What size is the fuel pressure selunoid line? I had trouble finding this and want to make sure i have the right size fitting before i go cutting the line. I think i saw mentioned in a thread that a 3/16th would work?

Should i find/buy a 3/16th T fitting on all 3 sides and somehow [ tips on doing this please..] shimmy up some adapter so my small boost gauge vacuum line somehow connects?

P.S. I read a few of threads on the T fitting, but none seemed to pertain to vacuum hose being as small as mine, and I DID look at one local hardware store and didn't find any T fittings under 1/4th . I still have got to check 2 more hardware stores, and an autoparts store in a little while, and figured i'd post for some hopeful advice/tips.
