I must be able to be done.

Picture?
Line diagram?
It's a pre-lube so it's +ve disp, so it's probably is above the oil level and draws the oil up...

I'm sure it's fine.

Both suction and discharge lines were below the sump level, and there was a flap check to stop oil drainage...
Interesting.

Hmmm?
