Re: electric fuel pump for outboards
Think about this very carefully. Yes, current EFI/DFI outboards have electric fuel pumps but the engines were "designed" to use them, and they still do have a primer bulb. If your engine is carbureted, think about what happens if the engine stalls. The pump will keep running. If the reason the engine stalled was because of a stuck float, leaky needle and seat or some other carb issue, you would pump the engine full of fuel which creates a prime candidate for an explosion. Also consider that should a fuel leak develop and you have an engine fire, the fuel pump will continue to feed that fire even if the engine dies. Usually under these circumstances, the operator will not think to turned the blasted key off so the boat burns to the water line and everyone in it is at risk. So why isn't it a problem on EFI/DFI engines, or your car for that matter? Because the ECU know when the engine is running or because the oil pressure switch has a set of contacts in it that shuts the pump off if the engine dies. Yes -- people add these but they don't consider the consequences. These engines have run for decades without the need for an electric pump. Fix what's wrong and be done with it.
