So, whats the latest on fuel lines??

While i have the engine out of the 308, i decided to replace all the fuel lines again(they were replaced 4 years ago). I used off the shelf for the small lines, and the unusual sizes
came from superperformance. While reading some old posts, it turns out the new fuel
is detrimental to current product that is available. So, do i really have to do this again?
What are the rest of you using? Has anyone noticed any ill effects with the current line supply? Is anyone else getting frustrated with owning an f-car?
