Hi, this is a video on a 2001 Dodge Ram 1500 EVAP Emission Control System leak repair for code PO442 small leak & PO455 large leak. My problem was found within the hoses on the top of the canisters beneath the pickup passenger side. I was lucky that it was an easy fix, sometimes the plastic lines connecting to the canisters crack and it is a more difficult repair but, very doable.
