Ok, I kinda had the same problem with my Impy when I bought a new drop forward meaning my current hose was way too long, anyways....
After buying a foot of hose and cutting it to about the length I needed, I put the hose into a bowl on boiling water and after about 10min I was able to bend it into the right shape and fit it to my Impy forgrip and max flow so that when it cooled down it was the righ shape, my hose from a side now looks like an "S" shape, would post pic's but not digi cam
