It was installed years ago with fuel line simply going to the fuel pump then to the carbs. The current 912 installation manual shows the fuel line going to a fuel manifold on the engine and a return line to the tanks. Do we need to modify our fuel installation to this manifold arrangement. Has anyone done that?

First, I put 900 hours on my first Model IV with the fuel system as you describe it. There was never a fuel issue. It ran fine and started fine. My new Model IV has the same design as before and as you have. I suspect the new design is to accommodate all the sensors that are available on the new glass displays - fuel pressure, fuel flow etc. I do know that there have been instances of vapor lock that the return line would help mitigate, but I never experienced it nor to my knowledge did any of the other guys I flew with with the 912. We would regularly fly in group flights and I don't recall instances where one of the group with trouble starting delayed a departure. I don't know if the vapor lock issue is model specific, but in my experience not an issue. I will likely go with the old design until I find a compelling reason to change. At present, I don't feel any pressing reason to have fuel pressure and flow gauges in the panel.
