LA dry sump plumbing?

Easiest would be to just supply into the block at the filter inlet, like when doing an external filter.

You can also plug the filter inlet (3/4x16 I think) and go in at the threaded hole (upper left in photo below) and tap/thread the original pump outlet and then plug (lower left).
