I had one of those glass filters on my model A. The screen is too coarse, stops big chunks, but a couple times every summer I would clean the carb bowl and find very fine silt in the bottom. Yeah, I know...tank should be cleaned but I drive the heck out of my cars and cleaning the filter is easy. Switched to a clear plastic one so I can see whats going on, with paper element inside, much better results. Frank, as I explained before, its easy, save your original line, make up a new one for the filter just to see whats happening. Easy peasy, couple fittings...some hose...two clamps
