Next step will be dropping the tank and replacing the 'sock'.
Verify you have 12v. electrical power going to the lift pump.
I would remove the FFM, clean it and then blow some compressed air through the water in fuel drain line, with the T valve open, to clear any possible blockage.

If you replace the tank sock, only use AC/Delco #TS 1012
