Recently was provided with a new to us from another location Fadal 40-20 that was needing a good deal of TLC. Looking for guidance on a Fadal Oil line retrofit for X axis for this 4020 model model 906-1 Serial no 930417

The Turcite was shot and has been replaced milled for initial flatness & oil grooves have been milled 2/3 of the Turcite thickness deep.

Now I am looking at replacing the oil lines and installing the chain retrofit kit LUB0071. Not sure where the T-fitting is intended to be place or where to tie in the chain.

Any chance someone may offer a guy a bit of guidance here?
