Replacement air bleeder assembly

I have a Pentair Nautilus FNS

FLT FNS48 DE

P/N 180748

Water has started leaking from where the pressure gauge screws in.  I tried putting a hefty amount of teflon tape on it, but it still leaks through.  I am not sure which replacement part goes with my pool filter.

You’re welcome have a great weekend!
