i got the instrument cluster replaced on my truck for nothing due to recall. when i had it in there my check engine light was on and they said it was something to do with the canister that takes the fumes from the fuel tank puts them threw a charcoal filter converts it back to gas and then puts it back into the tank or engine.


my question is:

where is that or those parts, are they hard to change, do i really need them!?

they told me it would be between 2 and 4 hundo to fix it
