In my case, the PO442 was a rusty section of EVAP line which eventually broke. I cut away the rust with a tubing cutter and connected a length of submersible fuel line ( Gates 3/8 SAE J30R10 ). Error code gone.
Note: I had to do the same for the fuel line, a few years back. It’s not concours material but it does the job.
