Onan Emerald Plus Fuel Filter R&R Procedure?

Hello - Need help, can't find anything anywhere online on this.

I am trying to replce my fuel filter (149-2333) on my Onan Emerald Plus 4000 generator. It screws into the upper housing (beneath the carb) and also into the metal fuel line below the filter (thread screws on both ends, male and female).

It seems obvious enough, but when trying to loosen it (lefty loosey), it is SUPER STUCK, and feels like I'm going to break it if I torque any harder.

Anybody have any tips on how to get this thing unstuck? I've tried torquing it both directions, it won't budge and I'm gonna break something if I go any harder, lol!
TIA!
