I don't remember your fuel pipe being like that Billy otherwise I'd have told you. Are you sure you're not confusing it with the servo (??) pipe that appears to be running around the front of the engine?

Properly, there's a little bracket type thing that attaches to the thermostat housing that holds the pipe away from any hot metal.

Based on high ethanol modern fuel and what it does to rubber fuel linings, I would most definitely replace any aging pipe straight away.
