Do I need to replace the fuel distributor lines in my CIS system? Options

[messick]

So, in my quest to get my "sitting for 15 years" 914 back on the road, I've already ordered new SS tunnel lines and new rubber line for the tank side and for connecting to the fuel pump, and for the connecting back to the return line tunnel hose.

Most of the engine bay stuff is already metal (or at least not just regular rubber fuel line) and looks fine. However, the lines between the fuel distributor and the injectors themselves is just plastic. Should I replace those outright? Checking other forums, and the fact that no one seems to just sell a kit to replace those lines, gives me the impression that those should only be replaced if they are actively leaking.

But, with that recent fire, I figured I'd ask here since I'm already in the middle of replacing lots of the fuel line stuff anyway.
