When there is no adequate pressure in the engine, it 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. The fuel pressure gauge illustrates how much fuel is getting to the engine. This type of pump cannot be used with a static (non bypass) regulator, because to stop the flow coming from the pump completely would drive fuel pressure to 100-PSI or higher, creating excessive current draw and heat, and potentially damaging the pump permanently. Notice I said no single fuel pump is suitable, well expand more on that in a moment. 1. These systems normally have one fuel injector per cylinder. What a pump does do is put out flow.
