The 1951 Kaisers & 1952 Kaiser Virginians were factory equipped with a fuel filter at the cross member area on the driver side of the car. Starting in 1952 later series cars, when AC pumps were used, they had the filter at the bottom of the pump. Some of the 1953 and later cars (without s/c) had Carters & the filter was at the carb. The easiest point to get at a filter (and best support for the mounting) is just ahead of the carb.
