Mikuni fuel pump does not have mechanical parts rather a rubber diaphragm that uses the engine's fluctuating engine crankcase pressure to pump fuel from the fuel tank to the engine's carburetor(s). It offers a constant and uniform fuel flow. These pumps have proven excellent and more reliable than OEM and aftermarket fuel pumps and generally used in applications which experience high acceleration. Comes with a pressure relief valve and a small return to tank port to ensure a constant fuel pressure and avoid carb needle valve pop off when at idle without having to have a continuous tank return line. This then allows for full fuel delivery with a larger needle valve seat inlet port size to better supply wide open throttle demand. These pumps are tested and recommended by Overland Adventure as the best aftermarket pump for your Africa Twin
Flow rate: 35 liter/hour.
