The current repro arrestors have a lower hole density. That makes them difficult to fill through with a fast nozzle. If you do make some screw-type arrestors use the original hole density.

Keep in mind a flame arrestor works as a heat sink to extinguish flame front propagation. You can't use just any thickness and hole size. After you make your prototype get some stick matches and test it in a tank with 1 gallon of gas and 9 gallons of vapor. If you report back, we'll know they work. Henry tested his.
