Dry-sump construction

in this photo mic posted, http://img167.imageshack.us/img167/2...bddsssadu9.gif , where the oil from the tank goes through the pump and into the engine, is it still going through the engine's internal pressure pump?.

if so will there be relatively high pressures in the line between the 3stage scavenge pump and the engine's pump? this is given that the scavenge pump will be moving a higher volume of oil then the internal pump.

are all your (bill) systems running gravity fed oil from the tank to the internal oil pump?

No that system uses an external pressure pump, and would typically feed the oil pressure in through the front or side of the engine.

My car has the pressure pump sucking from the oil tank, not gravity feed.

i meant 'gravity fed' in the context of the tank outlet being connected directly to the internal pump inlet, ie no pump in between

all good
