Not my proudest product but that plating was a pita to weld on. 10 an 90* bulk head and 8 an 90* bulk head. I didn’t have room for the nuts so I welded them. If I was to do it over again I will make a new top cover. Btw I have a vent but I installed it in the tank right beside the sender because lack of room. And yes my gas gauge still works.
