Hello, at the end of this module, calculating fuel system component sizes is mentioned, but it isn't gone into too deep. I just wanted to confirm that I understood it all correctly. Pump flow rate should be able be calculated from the equation mentioned in the video (BSFC*HP= Fuel flow), but then when looking for injector flow rate, do i divide that number by 8 (or however many cylinders the engine in question has)?

Thanks!!

It's actually the number of injectors you divide by. In 99% of cases this will be the same as the n umber of cylinders but not always so i thought I'd just clarify.

Makes sense, Thanks.
