Fuel filter location

I personally don't like see through filters because they're plastic or worse yet glass. You would never see anything like that from the factory for good reason and nothing and nowhere in the fuel system would you ever see plastic.

I agree to a certain extent. I think a plastic in line filter is not a good idea from a safety standpoint. I don't doubt that it's convenient to be able to see the fuel inside the filter, but after having a plastic filter leak on the glued seam and cause a fire in one of my cars, I'd go with a steel filter, and as much steel line as practical.
Nowadays, there is plastic everywhere in the fuel system, but I expect they are engineered to be more compatible with today's gas formulation.
It was a longtime ago, and i may be wrong, but I believe I recall clear plastic oem filters in pre '68 mopars.
