Finally got a hold of a RN hard water pipe. Thanks Matt.
I decided to use the RN pipe but after I had put everything together I noticed that the expansion tank line interferes with the fuel lines. Apart it came. You can see the upper RN pipe is shifted over just enough to be in the way.
Cut the down water pipe spout off and moved it to the N pipe.
Thought mig welding might end up rusting so I brazed it.
and all done.
I got so close to dropping it in this afternoon but was held up by the passenger side engine mount, I had ordered the wrong one.
