I worked a little on my SYE today, got the back half of the case back on and as I was giving it a look over later I noticed the oil feed tube going to the oil pump - looks like it dropped down out of the pump a little bit? I think the flange of the tube isn’t up against the pump. The tube is still there & I don’t see the o-ring so I assume it is too (it was definitely in there when I assembled it). Is this how they normally sit or am I taking this thing back apart?
