190 Loader Plumbing Confirmation

Finally have a joystick and everything mounted, looking to plumb. I read through this:

And think I understand open center and the concept correctly.

If I replace the union part "2" with 2 90s, then fluid would flow from pump through line "3", through elbow to loader valve in the red line. Then out of the yellow going to an elbow and line "7" . I have the power beyond plug, and this green line going back to tank. For rebustness sake is like the return to go through the filter, can I just do a T at part "15"? Or would it be better to just Tee off the drain plug?

Here's the sketch I made and forgot to post above.

Can't believe I missed that post!

Ended being almost exactly what I'm doing. But I decided to tap into the drain plug for return instead of at the filter. It's not as pretty, but I think it'll be simpler than dealing with the hard lines at the filter.
