I will start by saying I installed this oil feed with the entire intake manifold off, so it took me only 15 minutes at most. The flexibility will make any future turbo work a breeze, and it helps to remove potential leak points due to cracked hardlines.
Just remember that there is a thicker crush washer that goes between the banjo and the block to give clearance to the -AN fitting. Also, make sure that a flat side of the -AN fitting is parallel to the block when torquing the banjo bolt. I would've liked to see a little more clearance to the block but you will be fine if you follow instructions.
