Sorry to bring up another old thread... but did not see this addressed in any of the many threads that spoke about the NAPA 3039 filter
I have a '31 with the glass sediment bowl...
I acquired the 3039 filter and, indeed, it does fit in the glass bowl, on the shoulder very nicely.
My question has to do with the flange on the filter.
Has the hole in the center for the fuel to enter - and a series of smaller holes around the edge - presumably for the fuel to pass thru on it's way to the outlet.
The question is both versions of the bowl gasket (cork or the neoprene) cover the series of smaller holes... how does the fuel make it to the outlet
Seems like the gasket would be blocking the flow...
