There is a round plastic canister mounted under the hood on the left front inner fender. It either on top or it's underneath on the bottom. It has two hoses going to it and you will see a solenoid there to.

This where I do initial check on "hoses/lines" for damage as well as the solenoid function?
I was told there's 1 in the air filter housing (75$), 1 in the gas tank (175$ just for part!)
