Have the beast up on blocks swapping a 4 speed in and the broken auto out and thought it would be easy to get to the fuel lines right now, but need some advice.

Two related questions;

Will standard (checker, autozone, napa, etc.) fuel line turn to mush with petro diesel and if so, where can I just pick up some fuel line that's safe for diesel (oil.)

Will the standard fuel line out there hold up to biodiesel and if not, where can I get Viton in fuel line sizes and pressure rated?

Thanks for any info. Promise to take pics of the tranny swap and post soon.
