LLY injector leak

Alright so I just drove from Kansas to Arizona and during the trip I started to smell more of a diesel smell in the cab and also when I would stop and fuel. When I got home I found that the metal sleeve from the fuel line going into the injector on #8 had a small leak at the base. Nothing major but enough to make the side of the motor wet. Is this an injector problem or is there an o-ring in that sleeve connecting to the injector??
Thanks in advance.

by sleeve, you mean the fuel line where it connects I assume..? sure it's tight?, no o-ring that I know of. grab a 17mm wrench and make sure it's tight.

if the injector is down and tight, it may be the o-ring on the injector??????????

I had a small fuel "leak" on #8, matter of fact, and it was the o-ring on the injector, had to replace o-ring and washer.
There was a TON of carbon build up on injector body as well.
