Man I wish I had an answer for you but I don’t. I try like hell to just use an oil filter on the block where ever I can now. I avoid the remote kits like the plague.
If you are going to use a remote filter the best solution is to block off the filtered oil return in the block, thread the other return gallery and take the plug out of the other one.
That eliminates all the adapters and crapola like that.
