Despite a Fram G-2 gas filter on my car,(about to be changed out again) I'm having a problem with dirt in the carb. (previous posting) My duel diaphragm pump is the type with the glass sediment bowl on the bottom. If my memory is right (it often isn't!) these originally had a filter in them, possibly a ceramic one? In any case, are filters and gaskets available for these pumps?..Thanks.
