Sensor selection: petrol versus diesel
For a typical petrol engine without a fuel return line, the engine-power bands shown in the shop are a practical starting point for sensor selection. Confirm the engine model and maximum fuel consumption. For a diesel with a return line, size each sensor for the minimum and maximum actual flow in its own line — supply and return separately — not engine power or net fuel burn alone.
