I agree, there is no need to convert that engine to single line tank and fuel pump. Your tank looks clean inside…A new diaphragm, a gasket, and some fuel line is all it will take… In order to convert your engine to single line, you will need a fuel pump, single line tank/hose, and a bypass cover with pump mounting boss’.
There is nothing wrong with the two line pressure tank system, it is not dangerous, there is a pressure relief valve in the tank to prevent excess pressure build up.
The top of your pressure tank is broken, although it will work OK that way, you just won’t be able to wrap the line up neatly. But, I would consider replacing it anyway, since it is apart already. Just be sure to get one from a 6 gallon tank, the pick up and indicator arms are shorter on the 4 gallon tanks….Although, you can probably just use those pieces from your current top on a replacement.
