Do you need a pressure regulater for ppe fuel pump

There are basically two types of pumps used in automotive fuel systems, those that are pressure limited, for use with a static (non bypass) regulator, and those that are not pressure limited, and which must be used with a dynamic (bypass style) regulator. YouвЂ™ll see 900 lb/hr at 8 PSI is also noted for carbureted engines.

This doesnвЂ™t mean the pump вЂњputs outвЂќ 45 PSI, rather itвЂ™s telling how much flow is available at 45 PSI. When you read The A1000 flows 750 lb/hr at 45 PSI and 13.5 Volts, youвЂ™re being given vital flow data that is in the proper context. At Aeromotive we understand a pumpвЂ™s flow curve, across a range of pressure, reveals crucial fuel pump performance characteristics, so when we quote flow, we always provide the test pressure and voltage. Not all companies provide flow curves for their pumps, which makes evaluating that fuel pump for a particular application virtually impossible. And what it needs to do is put out the necessary flow, when regulated up to the required pressure needed for a particular application.ДЄctually, all electric pumps have a flow curve that changes with pressure. Though some pumps are pressure limited, which weвЂ™ll explain in a moment, the fact is no pump вЂњputs outвЂќ a set pressure. ItвЂ™s a common misconception for people to think that a particular fuel pump вЂњputs outвЂќ a specific pressure.

1.) IвЂ™m looking at an Aeromotive EFI fuel pump for my new carbureted engine, but I need 7 PSI and your catalog (or your website) says it puts out 43 PSI, wonвЂ™t this flood the engine?
