Are you talking about the hoses that connect to the filter? If so, your filter should have quick disconnects with plastic lines. If so, you should only replace those when they are leaking. The rubber fuel lines that are recommended to be replaced are most likely on older vehicles. Rubber fuel lines will dry root and leak so they recommend replacing them prior to that happening.
If there are other lines that you are talking about, get a picture of them and we will better understand. Thanks
