Oil feed fitting question - M42

[shEck3lls0]

I have a question regarding the fittings for my turbo setup I will be running on my m42. I will be running the supply off of the stock oil pressure sender switch. I know that that location is an m12x1.5. Now my questions are as follows.

Where can i find a correct T-fitting(or Y) to still run the stock sender as well as the supply for the turbo? All I can find is fittings with only AN and standard size fittings on them, nothing metric.

I also plan on running a oil pressure guage in place of the stock sender relatively soon. Is it adviseable to continue to run that switch, or will I be fine without it if I have a gauge? (I guess my question is, will this mess with how the engine runs? I will be running megasquirt)

Also, for the oil supply line (which I will get the size for you in a bit), should I be running a reducer to keep the pressure down? Or will it be fine without one?

Thanks in advance. :)

You could run that part.

And the restrictor is a must when using a ball bearing turbo, or any gt style turbo. However, I've run -3an oil lines to journal turbos and there were no leaks.
