TRS oil cooler line fittings...
 

Are there any restriction issues with these stock fittings? the lines are 5/8" and the fittings are big, I am chasing some issues that could be oiling and want to know how these fittings are, they have been fine for 21 yrs but just getting opinions.
Do they make a nice radiused fitting so I can keep my stock hoses?

Hello,
You want -12 or run the bigest lines you can do not run anything smaller than you have now. I have to replace all my line too. do you have a parker store around they will help you.

I am not looking for smaller, I am just making sure this should be fine, like I said, it is factory 400 Merc.. I figure it should be fine, i can redo oil system over winter if needed, I cannot get into it now being in the middle of July.. $$$$

Your stock oil lines are fine.increasing in size will not change anything. The bell housing cooler will only move so much oil. Good luck with it....

what about the oil adaptor? any flow issues?
