If you use copper, remember vibration flexing will crack it - you will
want to rig up spacers for the annular space to keep it either

Already thought of centering, and the whole center piece would have to come
out as one unit in case of problems. Did not think of the cracking, though.
Might have to have a short piece of hose made custom.
