what is the best way to run oil lines for the turbo. I have seen a t fitting where the oil sending unit is by the oil filter into the top as the feed and a large line staight to the top of the oil pan. I have a sandwich adapter for the oil cooler and has two holes on the side. Has anyone used this holes to send and recieve oil or just use them as the oil pressure gauge and temp gauge. Any advice on best way to run these oil lines would be a great help. trying to finish this project for my brother by ran into a stand still. I also have what he got as a return line. the line is the same size as the feed line which looks to small. from what i have seen the return is about twice as big as the feed. let me know thanks
