A few weeks ago my 570 quit on me. Located the problem to the in tank fuel line that was leaking ergo no fuel pressure and no start. Replaced the hose with a auto parts store regular tube that took me through the weekwnd. Now that one is disintegrating since it is not made for in tank use. KTM doesn't sell the hose separately it is only included in the 350€ pressure regulator. Any clues for sourcing a replacement fuel line?
