Default Where to tap for boost pressure

Hi everyone,

I am about to start with my methanol injection install and need to get a signal for boost pressure. Normally its pretty simple to tape into a rubber vacuum line, however with the 991.2, most of the lines are nylon plastic type. Does anyone know the outer diameter of the white nylon tubing lines? I am thinking to tap from either the MAP sensor or the fuel pressure regulator but curious if there is a better spot.

Which kit are you installing? Does it have to be manual boost or can it use electrical input? My initial thought would be adding a T by the map and make it look just like the OEM connections. Could even use OEM hardware.

Snow performance 210 (with the gauge). It’s a boost signal that goes to an electric sender. I was thinking to use a push to connect splitter but the line is 1/8 tube for the sensor. I am not sure on the factory line size and want to make look oem as possible. Anyone have part numbers for the oem splitters?

I believe ID is 5MM on the OEM stuff. I dont have a part number. So OEM stuff wont work.
