After sourcing and having the cylinder replaced, my octopus almost immediately packed up. Which eventually lead me to replace it with a home brew job. I replaced all the pipes from the Octopus and made a new manifold system up next to the LHM reservoir. As can be seen here:

However, the rubber of the octopus didn't actually seem to be in that bad nick. It just wasn't holding on of the suspension breather pipes in.
Now after about 50miles, more LHM on pouring out on the deck. I assumed it must be one of my pipes failing. But in fact it wasn't, one of the original rubber breather pipes that comes off the right front suspension had blown off. The pipe that had come off can be seen in this photo:

at the top of the photo. The Black dirty pipe that connects to the brass fittings going on down to my blue replacement pipe. I've fixed this with some spring clips.
So. Finally, my question is: Could there be something else going on here? I assumed that the OCTO had failed, but maybe there was actually just too much pressure building up in my return pipes? Could that cause the original return system to blow? I wonder if 50miles down the road (hopefully after the MOT that it should be getting tomorrow), another pipe is going to blow off.
Any suggestions or reassurances that I'm doing the right thing would be welcome.
Thanks!
