I’ll have to get under there and check but prior to this issue I had a p1441 code before and two months ago I did a smoke test on the system and found one of the lines past the fuel filter for the evap was leaking. Changed it and smoke tested with no leaks and code never came back.The part you are showing in the picture is a filter that keeps dust and spiders (or, at least tries to) out of the vent control valve attached to the evap canister, which is also in the picture. The one hose goes to the frame rail where it vents and the other hose goes to the vent control valve on the canister. P1441 is a small leak in the evaporative emission system code. The canister is filled with charcoal bits and is used to store fuel vapors from the fuel tank until a time when the engine is running and those vapors can be sucked into the intake manifold and burned in the combustion process. The vent valve is normally open, but the ECM will close it when it wants to test the evap system for leaks, using the evap pressure sensor. There shouldn't be any liquid gas inside the canister to the point that it is being seen coming out of the vent control valve filter because, as I said earlier, it's used to contain fuel vapors. Perhaps the fuel leak is above the canister, i.e. a rusted fuel line, leak at the filler neck or at the top of the fuel tank or fuel sender, and it is running down the hose to the canister filter?
