As noted previously, I decided to replace the fumoto quick drain with a Saf-Air P5000 quick drain. This gives piece of mind as the saf-air is easily safety wired.
Remove fumoto quick drain.
Apply Loctite 567 to saf-air quick drain and install. Clock safety wire holes.
Safety wire saf-air quick drain. I used a tab washer on an available bolt to provide a safety wire point.
Safety wire the plug in the upper tee. This gives piece of mind that the plug will not be able to vibrate loose.
