Anything that is capable of straining out the "rocks, marbles and bowling balls" that are capable of damaging the oil pump should work OK, as long as the pickup tube for the oil pump remains at the right level to suck up oil that's even with the "add oil" mark on the dipstick. I have fabricated many pump pickup screens from the leaf filter mesh that fits over household gutters, and run them on high-revving round track race engines. That "bowling balls" quote is from a Carter Carburetor training manual from the late 1940's, describing the strainer screen on a fuel tank pickup tube, BTW!
