Here is the "Cross Over" Hose I make up for clearing headers and custom turbo exhausts......
It connects at the Oil Cooler as the 911 107 739 10 "Cross Under" Line does.
Unfortunately, my oil Hose assembly tools and fixtures are still packed away for my move to NH, so I cannot make up new ones any time soon. I am now making tunnel lines & fuel hoses, and hope to catch up with oil lines within a few weeks.
