I am going to run it through some guttering along my garage wall so its always kept straight, then im going to invent some kind of attachment i can out on the end for filling it without kinking
Why not just run some straight pipe through the guttering along the garage wall? Why use something flexible
inside some guttering so it stops being flexible?
I must be missing something here. I thought you wanted flexibility. I promise I'm not having a go, I appear to be missing the point.

P.S. If you can stop it kinking, you're a better man than I am, Gunga Din.
