I was drilling some holes in the bottom of my stock intake box, and accidentally hit the windshield washer fluid tube, and cut it a little now I have very poor pressure on the right nozzle, and it is leaking can I patch it somehow or do I have to get the dealer to put an entire new tube in?

 

Take it off, empty it, and clean it up real well and use some J-B Weld on it. It will patch it just fine. Make sure you use something to cut any grease, oil, etc. Brake Cleaner works great...

 

Wrap some duct tape around that bad boy! Head to your nearest hardware and buy a union or something that you can slide inside the tube to join it back together after you cut it in two pieces. Course, make your cut at the same location the drill bit hit it. If you can, find something large enough so that the tube will have a tight fit. It may eliminate needing those small hose clamps.
