I agree. Do a search on my name and fuel lines and you will find a thread I posted with photos of my fuel lines after using B100 for a year. The gist is that the lines looked just fine. I purchased Vitons and that is what is on the car now, because I had them. But if I had to do it again I would buy MB fuel lines and I wouldn't worry about them. I spend nearly $100 on Vitons from greasework.org, but a set of MB fuel lines will cost half that.
