Bosch OE Aftermarket Fuel Pumps are engineered, manufactured, and tested to the same rigorous quality standards - and built on the same assembly lines - as our 'Actual OE' fuel pumps. Innovative, patented Turbine Pump technology virtually eliminates the fuel pulsation, noise, and hot-start problems associated with older pump designs. Designed to operate in extreme temperatures and under low fuel conditions to ensure reliable performance and an extended service life. Every Bosch fuel pump is 'end-of-line' function tested before leaving the manufacturing facility to ensure highest quality and performance for superior customer satisfaction. Pumps are designed for simple DIY installation - instructions included.
