I've been on many sites that sell the whole fuel pump system, but on almost all of them they are out of stock on a specific piece "Fuel Adapter Part number 204560066" and the sites that do say they have don't really have it. I've placed orders on them then they refund the money and say sorry. Is there anywhere that I can get this piece? Seems silly that my boat gets turned into a buoy because a part ceases to exist.
