Hmm, I recently bought a 5 gallon PNR tank that was still in the box it came in.
Pulled it out to take a look and this is how they rigged it up.
Imagine my surprised just now when I pulled the hose off the fitting that went into the tank.
The pump inlet does appear to to take an an orb or oringed fitting of some sort.
I guess it beats the other method of using a ton of filler to try and seal it up when you don't have a proper orb fitting to go into it.
