EHPS is a bit more complex in the plumbing, etc. Reservoir a distance from the pump has a straight enough hose, but from there it's a different animal.
I've never had to add beyond the little bit that happens in the first few weeks of ownership after all air is worked out of it.
3 of our last Jeeps required some added (only in tiny amounts so the bottle will last me a lifetime) but none of the others ever did.
Once added shorter after taking ownership and driving a few weeks, they've not needed any since.
It's also very possible that the fill at the factory is just to the minimum mark - meaning it's going to look a lot lower when cold, and after some driving once the tiny bubbles are worked out, it will be below minimum.
I've noticed on every truck I've had - there's a huge difference between checking it 3 or 4 hours after a drive on a 70 degree day, and checking it after sitting overnight when it's 50 degrees. That's normal. These fluids expand and contract - ever wonder why they want transmission fluid levels checked at certain temperatures - even on the older transmissions like the C6, C4, TF727, 998, 904, THM 400, THM 350 - they say "check hot". Hmmm, why?
Too many dolts don't read the book, pull the stick out cold, gee, it's below the add! So they add a quart or two then after a long drive, it's kicking fluid out the vent.
My point is - even PS fluid levels will vary with not just the air temperature, but the fluid temperatures. So don't fill it after a drive and 90 degree air temps and then think it's low again when it's been sitting in 50 degree temperatures.
