[stickshift]

My '31 AA truck came with only a 90 deg. brass shut-off valve on the firewall and no glass bowl. The brass valve screws directly into the tank through the firewall. I don't know what the original setup was, but I added a good see-thru fuel filter inline before the carb. My carb (zenith) also has a screen at the input fitting. Since this is gravity flow, the filter should not be too restrictive.
