I use the black nylon type AN hose on a recent motor, I had to fight all of them (Fragola fittings and hose) to get them seated all the way, I even heated the hose up with a electric heat gun and then hot water runaway
Some stainless hose and ends are harder to work with than others, I now use the cutoff wheel to cut 2/3 to 3/4 way through the hose one way and then flip it over and start a new cut on the other side so the cut off wheel doesn't push against the stainless braid outside edges when it is done cutting thumbs scope
