Civic EG

ok so i have a 92 hatch with a b20v. im tuned on 93 rite now but im trying to switch to e85 soon. i already know that i need bigger pump and injectors that are 85 compatible. but does anyone know if i need to change my fuel lines because ive heard they will get corroaded.
any help would be great thanx.

2+ years on stock lines without any issues. Plenty of people doing it for much longer than I have.
