The pump is 50psi and capable of 90 liters per minute. It has BMW style electrical connectors. If the 1100pump fits that stat it should work. I agree it sounds like a pump, but the sensor on the fuel rail tells the the controller how much pressure is needed, other wise it will pump at full pressure all the time. That I suspect is unique to the bike.
The word is that can be found on a few small cars.
