It is not easy to get too. The upper hose fas to come off at least. I am attaching a pic of a 318 with hose removed and the location from which it was removed from is circled.
I happen to have the MOPAR part # as you should replace it because it is difficult to get to.
Bypass hose [Mopar P/N H0063735]
I hope this info helps. Let me know if you need anything else.
