The Merc bleed system always seemed a little hokey to me, but I guess it's better than not using it.

My understanding is that for some reason fuel pools in the bottom of the intakes and the bleeds clears that out. The problem I see is that all this work is done by the carbs or EFi systems to precisely meter the air/fuel mixture, and then this is short-cut by dumping some random amount of fuel directly into the intake past that metering.

Is there a better alternative to this? ...like reshaping the intakes so the fuel does not pool, or rerouting all the bleed lines to the input side of the fuel pump?
