Why? Bubbles would rise via their inherent buoyancy through the pipes and exit without force.

Having the exhaust at a markedly different level causes problems. That is why Cousteau routed the exhaust hose around to end at a point next to the big LP diaphragm. Placing the exhaust above the second stage diaphragm would cause freeflow due to the pressure difference. That's how an airlift "vacuum" hose works.

Yeah, for a double hose I have to through my brand new scubapro g250v out of the window... At first I think I'll try something with a perforated inner bike tube...

I can tell you right now that it won't work. Besides, why wouldn't you want to trade up to a double hose?
