Summary for color anodizing braided fuel lines Discussion
Color anodizing braided fuel lines is generally not practical for the assembled hose Jeffrey Holmes asked about, because the question is really about whether the acid bath used in anodizing would damage the rubber-lined fuel line. The thread excerpt only includes Jeffrey’s question and does not show any replies, so no named answerer gives a definitive process recommendation. Based on the question itself, the key issue is that anodizing is a treatment for metal, not for the braided rubber fuel line assembly as a whole. Jeffrey was specifically trying to match a color in his engine bay, but the likely practical path would be to anodize only a removable metal component, if one exists, rather than exposing the complete fuel line to anodizing chemicals. Since no answer text is present, the thread does not confirm whether separation is possible or advisable.
Hello. I am looking to see if at all possible to anodize braided fuel line. I was wondering if it’s possible to do it. Due to the braided rubber. Would the acid bath destroy the fuel line? Would I have to separate the fuel line from the rubber and then anodize it? Looking for a specific colour to match my engine bay hence why I’m asking.
Thank you.

A. Is the braid actually aluminum? Most are stainless steel.
It would be very difficult to anodize braid. There would a problem of little/no anodizing where the strands overlap, and rinsing would be a bear.
And you’d have to remove the braid from the assembly.
