Good evening! Thank you for the informations.

I dismantled the mysterious part, it doesn't make sense in my eyes.

The filter installation has now been completed. Yes, there were a few twists until the copper pipe fit exactly. But the conversion kit is precisely manufactured.

The M & H oil filter is not optimal. It has a non-return flatter valve which unnecessarily obstructs the narrow-breasted oil pump. I am therefore looking for a suitable filter without a fw valve.

I will report!
