As Cliff mentioned, I use the marine micro screen filter in my Firebird Q-jet. With the stock AC Delco mechanical fuel pump it feeds the engine perfectly. Plus it's cleanable. I pull it out every couple years and just rinse it off. Actually now that I think of it, I haven't done that in probably 4-5 years LOL.

There is no need to add external filters anywhere. The sock in the tank, and the filter in the carb is enough. Keep the stock steel lines as they are.

As mentioned, the mechanical pumps have a hard enough time pulling all that fuel from the tank, the last thing you want to do is put a filter on that side of things. The sock does well enough.

You start adding more filters in the system and you'll find fuel starvation issues with the stock setup, it just makes the pump work harder than it has to.
