Fuel Pump 0628-1B


The original fuel pump from Walbro, as used on the 900ie, is out of production, and only a few are available. The alternative pumps mentined below, are not one to one replacements, but can be regarded as usefull alternatives. Sometimes some work has to be done to make the pump properly fit the connections and the mounting frame.

When replacing the fuel pump, the most important points to look at are:
-Pressure (system pressure is 3 bar, regulated by an adjustable (but sealed) pressure regulator. I am told the original pump can
deliver 5 bar so it doesn't have to work that hard)
-Current draw (the lower the better)
