When I replaced the AOS the hose between the top of the AOS and the intake manifold was so stiff I could not reattach it. What I ended up doing was to cut the tubing from the 2 end connectors (including removing the ends of the tubing where they are fitted over the connectors)...
... and joining the the original tube to the connectors with pieces of 3/4" silicon heater hose.
I will have to wait to see if the fit is snug enough without a sealant.
This should also work for repairing the long hose from the AOS to the front left of the engine.
UPDATE - after a couple of hours of driving there is no indication of the tube leaking. I will continue to check it
