It’s rust. You need copper lines. American Grease Stick - available at Advance Auto. Good product. You can bend by hand - carefully, but doable. I used this on both an e38, and a r53.

For sure you will need the line to that junction, and a new flexible line. Look at the rest carefully - that won’t be the only rust ( in most cases ). COPO Nova? What year?
