Hey guys, i was wondering if i could use the metal fuel lines, the ones found under the car, for oil feed and return to the turbo I can purchase them and bend, flair them to fit, but i wanted to know if it would be possible and what size of feed and return should i be using?

 

You can use hardlines, but you'll need to flare them and all that. The drain should be at least 1/2" I.D. and the feed would be in the area of 3/16.
