I just replaced both of those today.
Rubber Boot 13-71-1-247-031 $38.00
Air Hose 13-41-1-247-782 $6.63
The air hose had to be special ordered though.
It's not awefully hard to put in, if you take that small cover off you can use a flat head screwdriver to help push to old hose off the nipple while pulling on it.
Then use some lithium grease on the small end of the hose and push / twist it onto the nipple and ta da.
But if that doesn't work the intake has to come off.
Hope this helps.
