guys i need help to identify which metal lines into the bay do what, i know ones fuel in, fuel out, and breather but my cars been apart that long i dont know which is which!

bottom one im guessings fuel in because the rubber hose went to the top of the fuel filter, so can anyone help identifying the which of the other two (top and middle) are breather and return?

cheers!

 

Breather is the smaller of the two

 

brilliant, thanks Steven
