Replacing tornado tank sprayer. Best adhesive/loctite?

Replacing the camco tornado tank sprayer that has developed a crack.

Using the same screw holes to mount the new sprayer.

Do you guys think I should use some adhesive or loctite like material to help secure the sprayer to the tank?

Maybe something on the thread of the screws?

I will silicon around the edge of the sprayer but maybe used plastic expoy as well?

Thank you for your time.
