Reply To: Fuel Pump recommendations for Johnson FD 12 conversion

[Bob Wight]

I just completed a fuel pump conversion on my FD-12 and used the Sierra 18-7350 pump.   As Frank noted, you need the intake bypass cover from a 1960 or later motor, OMC part number 307477.   Some folks have also fabricated an aluminum adapter plate to use with the fuel pump in lieu of the factory bypass cover.
