fuel flow issues?

one my 2nd fuel pump in 2 weeks and still having stuck needle jet issues,..figured i had rust and trash in tank and went to look about dropping it and its plastic, would it still be subject to rust?? is it worth pulling to be sure or move on to replacing rubber lines and assume there coming apart in side causing my issues?? slantsixdan????

Any steel or rubber line in the system is susceptible to rust and disintegration.
You also might change the needle and seat just in case.

A generic thought is that if it is junk getting in the needle and seat it almost has to be coming from the line between the filter and carb.
