Turbo oil return line, need ideas on what I can use

What's the thread for the T on the oil pressure sending unit?

[tsuter]

The idiot light screws into an existing fitting that screws into the motor. The sending unit is a 24mm and the fitting a 17mm. Remove both. Screw a 1/8 Pipe Nipple into the existing fitting and a 1/8 Pipe Tee onto the nipple. The sending unit then goes back into one open end of the Tee and a 1/8 Pipe to -4 Fitting into the remaining open end for connecting the oil sending line.
I don't remember the thread but I took the existing fitting to the plumbing supply house to check 1/8 Pipe nipple.
I have a lot of pictures and all of my turbo set up at:
