Holding Tank Filter - Fluid Trap

I'm gonna admit, I feel this fliud trap is gonna be an over-kill. But I won't be able to verify that till next year when I check it and clean it out if necessary? The reason I think it is overkill is because of the vent line "new elbow" and re-orientation that I also did. But, That turned out as an "after effect" because I couldn't mount this fluid trap the same way the original vent line went in. So, my original idea was to intercept any fliud from the tank below from entering the holding tank filter.

These are all the parts for it.
The filter and trap together.

Just the fluid trap.
Just the filter.
