I need to ditch my evap. canister. Yes I know what it is for, and what it does etc. etc. Long story short it is coming out. It is in a valuable location, and relocating it just takes up more valuable locations. My question is, "This is the part I want advice on " I plan on re-routing the vent tube and putting some form of check valve in it in case the truck happens to land on its roof. I do not want gas pouring out on my lit cigarette . So I am looking for a check valve that is made for this purpose. If anyone else has ever done this I would like to know where you rerouted the vent to.
