When 19 gpm hits an oil filter that flows 12gpm,the bypass opens and you ain't filtering s#$%!!



first let me say i'm not trying to start a peeing contest and i myself wouldn't want oil bypassing the filter. that said regardless of how much the pump flows it is the amount flowing through the engine that has to go through the filter. any more than that only gets pumped in circles from the pump discharge through the relief valve then back into the suction. imho there are very few engines that are going to flow what the pump does. i know Andy Finkbeiner did research on different pumps and he may have some accurate info as far as how much oil these engines are actually using. imho as mentioned using screens on the pump suction is a good.
