Fuel pump choices?

RB,
You get the Gold Star for ignorance!! I am not going to waste too much time on you because you will never get it.....
All my comments, now & before, are based on NA engines. Forced induction changes things.
The displacement AND max rpm determine the total airflow. That was provided by the OP so that the calculation could be made. Once airflow is known, fuel flow [ requirement ] can be determined. Allowance has to be made for VE [ misnamed, should be mass efficiency, but everybody is used to using VE ].

If you don't like typing...don't type. We will all be better off....
