Why did the hose leak? Did it have a hole worn in it? It is common on various types of equipment if it has been rubbing anywhere. You can use pieces of Heater hose cut to length and slit so as to slip over the hose. You may use other things like pipe insulation to protect it in critical areas. Zip ties will hold it on.
If its the shiny plastic type of hose it wont tolerate sharp bends as well as wire reinforced rubber hose. I would guess that it's the shiny plastic hose as it's usually less expensive.
