O.K. At this point I admit I'm no doctor of physics. I also have to
admit it was my idea to install the top fill bung thinking it would be
easier to fill because I wouldn't be filling against a barrel full of
water. So I lose the argument. HOWEVER... I also want to leave the hose
attached to the top fill bung so I don't have to re-attach a water
filled, running, hose back to the cabin.

Thanks!

Re: OT: Physics/hydraulics of water and barrel
 

LOL!

Water is heavy. How many PSI comes out that bottom hole?

The pump must first overcome this pressure before it can start filling
the tank. That can easily mean the pump will 'run backward' and fill up
the truck if the top tank has enough weight in it.

It will work. At my cabin (no electricity) we have a 500 gal drum on a
30 foot platform. It fills and drains through the same 1" hose.
No problems at all.
