I got the new tube from Inline Tube. It is a VERY close to perfect match. I test fit it on my extra engine and it will require a very minor tweak at the water outlet at the front of the intake. Nothing worth bringing to their attention.
I really like these because duplicating the really tight bend at the very end of the line (turbo side) is difficult to duplicate if you make your own. To make your own that tight you have to bend it first and then cut it off and flair the end but most flair tools can’t have a bend that close to the end.
