Oil cooler ?? Gear ratio ??

There is apparently some variation in the adapter positioning. Last weekend I connected my oil cooler and filled it with oil. Few days later I noticed a pool of oil under the bike. Seemed to be leaking from the O ring on the adapter. Took it apart yesterday seemed to be no apparent issue and put it back together. Today leaking again. Took it apart again and back together with new seals on the oil fittings still leaking. When you put more pressure on to tighten it goes almost horizontal which is a no go to get the lines connected. I had purchased another cooler last week for $18 (I appreciate it when things happen for a reason) so I in fact had another adapter readily available. I put that on today, the inlet hole for the oil pump is on the top on this one when it tightens. See if it it will leak. Chinese parts are cheap, but they are sometimes cheap for a reason.
