Wow... I feel fail... I completely missed this thread somehow and the other ones linked (which are failed links now)...

Fortunately when my engine blew last year we put all new o-rings on top and bottom of the injectors... as the tech and I are perfectionists and didn't want any leaks.

Unfortunately I just crested 95k and the fuel rails have been disconnected multiple times (LIM repairs, gasket replacements, new engine, etc...) and the Quick Connect O-rings have never been replaced... someone say a prayer until I get them changed .

I haven't as of yet smelled gas or noticed any leaks and I'm always checking fluids and playing under the hood, so I would notice... altho I DID remove the SC Cover and Hood Insulator, so fumes would probably just dissipate before I ever even noticed them. I Need to look into this
