Its a little tough to get good photos, but here are a few.
1. Side view of adapter block that is mounted on the oil pan.
2. Rear view of adapter plate
As I understand it, the adapter block is a custom made part for SMB's. It does not show up in any of Amsoil's literature that I can find.
3. View of oil filter block. The black filter is the bipass filter. The white one is the full flow filter. The hoses in the front lead to the adapter block. The filter block is stamped on top (need a mirror to see) for which way the oil flows. The adapter block is not marked, which is probably why things got messed up.

This is where the check-valve is located. The plug was too tight for me to remove so removing the check valve will have to wait for another day.
After talking to Jim today, and confirming with a pressure test, I swapped out the hoses. I swapped them at the adapter block end. They were really stubborn to get off. Jim recommended using teflon tape on the fitting threads and a dab of grease on the ball of the fitting to make future removal possible. He also recommended a full oil and both filter change at my next PM. Both filters are now warm to the touch.
I mentioned to him that the bipass filter works its way loose after awhile. He said the bipass filter gasket is the culprit. It doesn't set like gaskets typically do. He said to use a fabric type filter wrench at the top of the filter and tighten it as hard as I could.
I have an email into Peter at SMB West. I look forward to their explanation and resolution.
Thanks again John for this discovery.
