When under my hood this morning, I happene dto notice both my fuel rails have become discolored from heat! I havent noticed that before, and went over to the GF's maxima, and at almost 100k, hers look normal. Is there something going on here that I shoud be worried about?

 

My 97 did that. The only one at an ATL meet that did, if I remember correctly. I just ignored it and never had any engine issues.

 

It shouldn't be an issue. It's not like the fuel is hot when it's flowing through there.

 

OK, cool. I was just worried that maybe the injectors were getting hot or something.
