Hi! I purchased a 1958 Dart Arkansas Traveller with the above motor at an auction last week. Seller said it had been used regularly and maintained. Didn’t know much else. I don’t know anything about it either, but am researching/learning. I discovered that this motor originally required a pressure tank, but many folks convert them. Looking at the motor now, I see what looks like a modern fuel line connection. I also see a new-ish black gizmo on the side of the motor (see photo). Could that gizmo be the thing that eliminates the need for a pressurized tank system? Any advice would be greatly appreciated. Thanks! Matt
