JR,
Good photos! This filter installs "backwards." When I say that filter are "supposed" to flow from the larger surface area "outside"
to the smaller surface area "inside." This filter is installed "backwards;" the flow enters on the "inside" and flows to the
"outside." It doesn't take a lot to plug it up!
That's why Ken Frey's idea of installing a filter in the rubber line that connects the metal line welded to the front crossmember
and the inlet to the mechanical fuel pump:

Here are some good pictures of the fuel filter and how it is installed. You can put them in backwards, ask me how I know!
