that would work but that let's the tank vent, might build up pressure. If nothing else run some rubber line on it under the bed away from exhaust and put on a breather cap and let it breath, then cap off the tbi up front. if it's been that way and it's not been putting gas smell.fumes in the cab then maybe not worry about it at all then. or look into a vented cap then plug it off.
