Vapor Canister Howling

[REDSOXTICKET]

The charcoal canister is making a howling noise when the rpm is steady then disappears when the rpm change + or -.
Upon inspecting the canister the noise is coming out from the air drain hose. While an assistant was pressing the accelerator at steady rpm I was able to stop the howling noise temporarily by hitting the canister with the handle of a large screwdriver.
Afterwards at about 500 miles I got a P0446 and a P0441 or P0443 or both which I forgot now.
Any reset the error codes, banged the canister, drive 1.700 miles then again the light comes on with the error codes along with the howling.
I had my car inspected and it passed with only one system "not ready" which happens to be the emissions system monitor. If the car had two system monitors "not ready" it would have failed. Your allowed up to one max not ready and it will pass in my state.
If you like to discuss this issue fine.
However I will be looking at some time to replace the canister along with the vsv as an entire assembly.
Does anyone know the part number for the entire assembly that includes the attached vsv and other components that make it a complete assembly?
I am trying to find the best price. Is it wise to purchase a canister and vsv separately and do I need any other component other then the vsv?
I found two canisters with different numbers, confused and I need your advise
