Well mate, I'll be going down to the folks not this weekend but the following, so I'll pick up everything I have, that's pipe hoses and cooler, I believe the pipes are not aluminum, I think there some sort or light steel with crome coating, basically the same as what I have on the line.
However, I might go down this weekend and pick them up as the boy is with the grandparents and I have a feeling I'll need to get him, I'll let you know mate, but I think I have enough pipe to do the kit for you
