Is there no problem with the engine pulling the pipe when you accelerate with load? Just one question that came across my mind when I was thinking about it.

 

This is a trial run. I have $20.00 smooth wall flex tubing so I am not going to use anything for the engine movement since the hose will move. If everything fits good and I am happy with setup i am going to change to smooth metal tubing with a couple of silicone hump connectors.
