Bosch aftermarket Fuel Pump Assemblies are built and tested to the same rigorous quality standards as our OE fuel pumps to ensure a long, reliable service life. Patented Turbine Pump technology, incorporated into all of our pump assemblies, virtually eliminates the fuel pulsation, noise, and hot-start problems associated with older pump designs. Bosch pumps are designed to operate in extreme temperatures and under low fuel conditions to ensure reliable performance and an extended service life. A new fuel strainer is incorporated into each fuel pump assembly (where applicable) to prevent contaminants from entering the pump - preventing the main cause of premature pump failure. In addition, every Bosch fuel pump is 'end-of-line' function tested, before leaving the manufacturing facility, to ensure highest quality, superior performance, and customer satisfaction.
