sorry, i misunderstood. i see its a seperate piece, not part of the pres hose. and i believe the p/s pressure hoses that join that "T" use o-ring fittings to seal to it, not flare fittings. from looking at the sensor on rock auto, like you said, the sensor has two o-rings at the base of the thread. the thread looks like it is straight, not flared like a pipe thread. if it is a straight thread, you may be able to match the thread with a tap and clean up the threads in the "T". i have successfully done with brake fittings and blocks. but it is going to be tough, due to the length of thread being as short as it is. i suspect the thread is metric but i don't know the pitch. if you do match it to a tap, try using a bottoming or blind hole tap, they have less taper to them and are meant to cut a square thread to the bottom of the hole.
or you need to find a replacement "T", junk yard, or fellow member may have one.
