And what it needs to do is put out the necessary flow when regulated up to the required pressure for a particular application. Some fuel injected engines even have two fuel pumps: one low pressure/high volume supply to pump in the tank and one high pressure/low volume to pump on or near the engine. The following method can predict the approximate flow available from two pumps, in series, at a specific pressure: To find the flow volume available from two pumps plumbed in series, at a desired pressure, find the point on each pumps flow curve where their volume is equal.
