My son ran over something that damaged the underbody fuel lines (supply, return) on a 2003 Jetta TDI Wagon. I searched several online suppliers as well as a couple VW dealers over the phone, and apparently these fuel lines (VW part no. 1J0-200-059-M) are no longer available. I'm hoping I can come up with a "fix" using some sort of "stock" plastic tubing (assuming I can find the male and female quick-release fittings that match those on the vehicle). Can anyone offer some guidance on how best to address this situation, i.e., what specific type of tubing to use, as well as a source for just the fittings? It would help me out of a pretty tough situation. Thx much.
