Required Fuel Pump Flow Rate & Pressure
@
*Injector flow rate must represent the flow rate at your base pressure. If base pressure is not 3 bar (43.5psi) please use the flow vs pressure calculator to calculate injector flow rate at base pressure. DW fuel pump "call sizes" are rated at 40psi. Please refer to the flow vs pressure charts in the links below to choose the best DW fuel pump for your application.
