Re:
Fuel lines. Use the existing supply & return lines. Connect the engine driven diaphragm pump to the supply line. No additional pumps required for carbureted operation.

Management. Carbed is simplest for initial operation.

Switch. The switch for the diesel engine has a vacuum shutoff section added; the electrical section should still have the ignition circuit contacts.

SLS. The pump is the same; reuse the pump from the diesel. The drive dog might be the same.
