The overflow tank (puke tank) has the following conections:
1. 3/8" line transmission and on some orginal cars their is a T on the transmission also going to the diff.
2. 3/4" line going to the back of the intake manifold. On some cars this is a clear line so you can see if their is water in the
oil
3. 3/4" line on upper right side is road draft tube
4. 3/4" line on lower right side is
oil return to the
oil pan
Hope this helps
