Hi guys , i just replaced my e90 n47 2011 model engine and now im stuck alittle bit . I will post 2 pictures for attention maybe someone can help me out with a video or guide or anything.

So, i have a pipe which goes from the fuel rail to the fuel pump and on the other side of the pipe i have the same exact pipe which when i searched on the net is called the fuel return line , and my problem is that i cant find where this pipe needs to go or else if by mistake i replaced it when attaching other pipes and now i need to know if it should go somewhere or i i need to remove it.
