It is just a b mod pipe. The bracket was for a dry pipe on a previous ski. I have since modified the front mounting lug so it is easier to get the tank in. I couldnt find a picture to show what I did . What I did was cut the lug off and epoxy in a lug as close to the hull as I could and I use a spacer the width of what I cut off. It makes it much easier to get the tank in and out. I will keep looking for a picture to post.Paul, what is that plate bolted to the top of the cylinder head? Also any special tricks getting the b-pipe to fit? Unless you are lucky and have the FX-1 b-pipe!
