After much fannying about l decided to put aside the stainless pipe. It is impossible to get the bends correct to matched the other spigot. So reverted to a spare metal one
That why I said that you have to tweak the stainless pipe to make it line up with the elbow. They are all the same i.e. close but not right. No excuse for it really.
I'm sure that I have detailed it in more than one engine build topic.
