that is the evaporator/charcoal canister for the fuel system I would leave it alone its connected to that line coming from the canister on your firewall along with the tank vent.
its not really worth the effort to remove it for the tiny bit of space you gain. you would need a vented gas cap and a place for those fumes from the front to go after you removed it. I took mine out but I had the cab and bed off so it was easy that way to remove the lines and everything from it and get a vented cap,
