He's not OPYou are the one that has not even clearly stated what you are talking about in your first post. Multiple of us have also given you sound advice if you are talking about a charcoal fuel vapor canister. If you are so dead against it, plug the engine side, attach a fuel filter to the tank side connection so that the tank can vent without getting dirt or other debris into it and carry on.
