In-tank Fuel Pump - BR300i

Bosch pioneered the development of a pressure-generating fuel pump in the 1920's, and development has continued until the modern era of high-flow turbine fuel pumps and high-pressure injection pumps. Recent innovations such as premium carbon brushes, anodized aluminium internals and asymmetric turbine impellers deliver high flow, reliability, low noise and effectively zero cavitation. The fuel pump is a critical component to the health and performance of your engine, so trust Bosch Motorsport’s uncompromising commitment to quality.

Bosch Motorsport's fuel pumps feature high precision internals engineered to deliver unmatched reliability and performance. Motor speeds within the pump can be as high as 10,000 RPM and the clearances within the pumping elements down to microns, thus great care is taken to individually balance the rotating assembly in every pump. Further, each fuel pump is tested post-production to ensure the superlative quality for which Bosch pumps are known.

The BR300i is little brother to the BR540 and was designed to meet the demands of performance vehicles with moderately elevated power levels due to turbocharging or other tuning. The 38mm diameter body is a direct fit for many Japanese, European and Australian performance cars from the 90's and 2000's.
