Can someone tell me what this blue tubing is for. Caught a rock and pinched it.

Does anyone know if the 1999 - 2002 windscreen washer jets will fit a 1995 - 1999 P38? Just seen them on eBay, and they look as though they would be much easier to install and remove. I'd also recommend that anyone who needs to replace the brittle rubber tubing tries using silicon tubing. It's...

I've ordered some flexible Nylon tubing to use with the second ViAir setup as the Poly tubing I'm using doesn't hold up in the engine bay. Is it possible to bend the Nylon to shape with a heat gun and pipe bender without weakening it?
