The new oil crossover line is one continuous piece of 3/16”copper tubing. It starts on the lower left in the picture at a standard compression fitting in the block using a standard compression nut and sleeve, it is bent around to thread thru the special compression nut and fitting in the upper right part of the picture and threaded through the water jacket. This seals water jacket and the feed thru on the drivers side.

It is then bent to clear the push rods and threaded thru the head and into the rocker arm shaft oil connector where another standard compression nut and sleeve terminate it.
The kits that the Advance Design vendors sell should have all of the tubing and fittings and instructions that you need to replace this crossover tube. Your local flaps or hardware store will not be of any help on this. As was the original crossover, this is a one shot deal and if for some reason you need to take things loose from the water jacket penetration then you will need to replace the entire tube again.
