Unscrew two clamps (one each end), remove old hose, transfer clamps to new hose, refit.
Couldn't be easier.
Clamps are probably screw clamps, but might be springy wire clamps - in which case, squeeze the wire ends together with a pair of pliers (multi-grips are good) which expands the wire clamp enough to slide it down the hose, allowing you to remove the hose.
Can you please post a photo of the damaged hose, in position, on your machine.
If I have a matching hose, and I almost certainly do, you can have it free, just pay the postage.
