Bringing back an old thread. Found a better way than ordering the expensive Sonnax kit (for those going with AN Lines)
46340A from transmission parts use dot com. It is the long special fitting, made for 3/8 inverted tube. Then you need a -6 to 5/8-18 Inverted Flare, such as Earl's 991947ERL.

Can you just buy 2 of each of these and they will both work with modification?

TCI says it is. Actually it is the same threads as a pipe thread, just meant not to have a taper and use an O-ring. 1/4 npt works just fine. Just don't overtorque it and crack the case.
