My quick connect line to the fuel rail is leaking fuel, The orange and yellow o-rings are chewed up, is there a way to replace the o-rings or do you have to replace the ends or the whole fuel line?

 

Check with Napa to see if they carry the o rings; my local Napa has a pretty good selection of fuel line related parts. Also a good idea to apply a little oil on the fuel rail "tips" when you reinstall the fuel lines.
