For street-driven applications, it can be beneficial to combine a smaller fuel pump along with one or two larger fuel pumps. This allows you to street drive on the smaller fuel pump which has a lower amp draw and does not generate as much heat. Once you get into boost, the larger pumps can be activated to support your high horsepower needs. The easiest way to do this is to use a Snow Performance Boost activated pressure switch (part # SNO-81014) and a Snow Performance Multi-Pump Relay Module (part # SNF-20003).
