Just a couple of clamps but the new pipe will be very stiff and it is best to try to make it pliable by soaking in hot water or using a hair dryer before attempting to fit it. There is also a push in breather pipe that goes through a spigot on the new pipe and this can also be tight.
Read the link that I included ( pity photos have gone ) and it will fill in the gaps for you
IF you think that this pipe may be overly soft.
