I don't know how it came up, but got videos about this fitting and how the OEM part deteriorates and will fail. So I decided to change that fitting without changing the hose and ordered a no-name brand aluminum fitting for @$24 shipped. Honestly, doing it that way looked sketchy. So I decided I should replace the whole fitting/hose with the same plastic OEM fitting and then put the aluminum fitting on the old hose as a back up part, which I was thinking I probably will never use because 150k+ miles... than I read OP's mileage...whoa!
Anyway I found an aluminum fitting with hose for $28 before tax/shipping made by Rein.

Seems the best route to take for this instead of getting another plastic fitting/hose or stand alone aluminum fitting, cracking the old plastic one risking getting crap into your motor and then cutting out the clamp risking cutting the hose.
