Hydraulics and flow of oil
We still do not have a hydraulics specific forum.
QUESTION: I heard, read, somebody said... The return line on a hydraulic reservoir "has to be below the fluid level or foaming will occur".
We have several different systems, at work, some below and some above. No resident experts. I've never noticed foaming in any of them, except when some air is sucked on the intake side of the pump.
I am in the process of building a 28 gal, 12"dia, vertical hyd tank for my splitter and my curiosity is churning. At this point it is a curiosity and not a burning life or death issue.

Hydraulics and flow of oil
I was hoping it was something like anti foaming... Now I am a little concerned about the moisture issue. But I'll cross that bridge after I start to work the beast.
It is a splitter I am building from odds and ends. See # 5&6. The frame is 16' now.
Any ways I found a small 4BT 3.9L Cummins with a 30gpm pump on it, in the back hedge row at work. Only had 25 hrs on it total been sitting for 10 years un-run. Had water in the crankcase...The price was right, "FREE" (well probably not free with all the FOT (freeOT) I put in), so I drug it home pulled pan soaked all the internal surface parts good with Zep 45. There was very minimal rust in side only some superficial surface rust. I pressure lubed it with a gal of oil. Fired it up. I runs beautiful...
Cutting up the rest of the machine for scrap steel.
Have reinforced the splitter beam. Going to add a 5X24 cylinder, 4 or 6 way wedge.
With the 30 gpm pump 20-25 gal hyd fluid will be on the light side but dooable. I do not plan to run it hours on end.
I'll probably send "Tim Allen" a photo 
To date I might have $300 in it Plus 100+ hours of tinkering, thinking and scheming...

Morning Randy
I was busy making an edit.
YUP I have looked at a old Jeep a couple of times now to find a small 8 speed Roadranger...
A 100HP turbo charged diesel with a 8 speed would be COOL!
