Change them now, or after it's towed back to your garage. Your call.
You might get a year out of factory fuel lines with B-99. Then they
start weeping. Then they start oozing all over your engine. Then they
go bad. If you run SVO, even less time. Had a steady vege "ooze" onto
a motor mount before i swapped lines. No more motor mount. Image what
it does to rubber under pressure. It's about $100 for the hoses and an
hour of your time and you don't have to think about it again.
It still applies... I think it is like 1998 or 1999 that they started with
the newer version but not all are like that so it is much safer to change
hoses... whether viton or Mercedes... stand a much better chance than
