'01 RX300 windshield washer leak needs help!

[Riverguy]

'01 RX300, the windshiled washer hose snakes up along the passenger-side hood hinge and from there disappears under some plastic covers.  The hose has developed a tiny leak right where it goes under the cover, apparently from 19 years of abrasion every time the hood is opened.  I'd love to get some tips on how to access the hose beyond the point where it disappears.  The leak is right there, but I can't get to it to repair it.
