Yeah there were three connections on the old pump, dirtier picture is old pump still installed looking down at it. The flare nut hard fuel line is out of view but I have that removed, then there is the yellow line that comes off with the nipple by losening the hex on the old pump, then there is a third connection with the ribbed end just next to the yellow hose connection and I had already taken this off in the old pump picture, it had a screw clamp on it.
The cleaner picture is new pump and I'm assuming yellow goes back on the ribbed connection (has plastic cap 1) and the flared fuel line goes on plastic cap 2 at bottom. This black plastic hex and odd plastic nipple thing on the side of the new pump look like the design changes, not sure what that side port would be for.
Bosch part

What are the pictures of? New pump and new pump installed? I think the other nipple is a return line?
Been a couple months since I changed the pump in my 335d so my memory is cloudy
