Back on the Dart today. I finished welding the sump on the original fuel tank. Then I cleaned it out and leak tested it with zero leaks. My kids spent about an hour removing the items my brother and I stuffed down the filler neck 30+ years ago. I removed the factory undercoating, prepped and painted it. I also had time to reassemble the heater box with the new heater core and all new foam, clips, and seals.
