I had this howling noise. I tried replacing the two purge valves, housing, and lines and it didn't fix the issue.

I actually tracked it down to an additional valve in the fuel filler (2000 Boxster S).

I've got the other two purge valves in the housing, with new lines if you want to try replacing those, PM we and we can workout a price.
