Just wondering if any here knows the size of the fitting that I can into the STAR T fitting for the oil feed line for the turbo. I'm putting the stock stuff back on and I don't wanna take the sensor out of the T because I think it might break and I wanna make it easier to put the turbo back on.

Its the part on the T that screws in between the T fitting and the oil line. Just wanna know the size of it and where I can find something to block it off.
