Currently finishing up a new build. Does it matter if the return (or ‘in’) back to reservoir is at the top or the bottom? I usually do return to the top, but in the current build it makes more since at a bottom reservoir inlet, basically an easier bend then routing to the top. It’s been awhile since I updated my build, so can’t remember if there was good reasoning for top return… like better priming or bleeding of air?

Thanks in advance
