Yes to all the above.I used a single nozzle in front of the carb located under the engine[updraft].It worked ok,but I am in the process of installing 2 points,one in each side on top of the engine.No data on this yet.Fuel pressure seems adequate with fuel pump off in cruise but use boost pump for take off and landing.
