If it takes any longer than the combined amount of time it takes to get it there minus what the engine is using then it will create pressure rise and the .060 is too small. If it doesn’t, it’s not. It’s that simple.
I know, I'm just sayin the factories used that .060" "or whatever it was" orifice in those return filters, so they musta thought it was enough. I have a WIX return filter with the orificed return. I should go see how big it is.....or how "small". lol
