I tried the large folded-paper filter on my Model A Zenith. It has a long U-shaped snorkel which places the filter below the float bowl. I removed it because if the carb drips gasoline it will soak the paper filter. When I become skilled enough to completely eliminate the possibility of fuel leakage I will reconsider it.
BTW - The most recent gasoline leak saga began when the float filled with fuel and the under-dash shutoff valve didn’t do its job. Gasoline came out of the carb throat. If the air filter was there it would have been soaked. Replaced the float. But in the process of removing the fuel line from the carb to replace the float, the glass fuel filter began leaking, with the fuel running down the fuel line onto the carb. Again, an air filter would have received the leaked fuel.
So until I’m quite certain that fuel isn’t going to leak I’ll continue depending on the engine pans to do their job.
