try posting a close-up photo? I used to think there weren't any markings but then I put on a pair of 2.5x magnifiers headgear and spotted them... and depending on the mold they come out of, often very faint - just little triangular dots not much bigger than the point of a sharpened pencil - but anyhoo, as I mentioned, I quit worrying about those and just see which way the air can blow through and let the fuel flow follow the same direction...
