If its not really really bad rust on the outside of the metal PS pipes..
I would sand and treat them....
like clean, then osphro, then primer, then a really good top paint like
Zero Rust ( or POR )

I believe the common replacement option is the full hoses deal.

either than or good used lines from a van that always lived in a very
dry climate. I've done that a few times.

gas tank has to be out to replace them ( 2WD ) .
