I guess it doesn't matter now; I'm just trying to figure out if it's ok to just weld the thru-deck closed.
you could just grind off the weld around it and knock it out,then weld a plate in the hole to leave the deck
welding the fitting itself closed will be difficult due to aluminium corrosion
issues.,otherwise unscrew it put a new seal in and leave it.
i have simmilar fuel
fillers on my boat,recessed into the deck
