How much fuel in the filter

Hi FABO!

1974 Dart with a /6.

I dont even know if this is an issue or not, since the car runs fine, but every time I take a look at my fuel filter with the car running it only fills a small puddle in the bottom. I also dont actually see it pushing any fuel in the filter, leading me to think its trickling in because the level doesnt drop. On my other A-bodies I have had I always recall the filters being 1/3rd to 1/2 full and if they were empty I remember them chugging fuel in there at idle or start speed.

Anyway, its got a new pump on it (previous owner installed) and a new tank, and again I dont know if this is even an issue, since the car runs fine, or something I am looking for an issue in (I have plenty of non made up issues to deal with lol), but should I be concerned at all?
