CRD Fuel Leak?! HELP!

So I purchased my New 2006 Liberty CRD a few weeks ago. We've loved it to death the whole time we've had it, but the last time I filled up with gas I noticed a strong diesel smell. I didn't think anything of it as the station but it followed me home and was strong all day. Tonight I noticed that there was fuel on the ground beneath the engine.

Long story short, I started from the top of the engine to start looking for a leak and found it right on top! I'm still learning all the in's and outs, but I really need someone to tell me where to start before the dealership takes me to the cleaners. I've got some pictures, hopefully I this doesn't mean the end of my Liberty named Lucy. Help!

Not a CRD guru, but from the pics, I can't see a source of the fuel leak. There are the injectors and the steel fuel line coming off them. Need to look for stains to see where it's coming from exactly.

You probably have a leaking injector connection.
That is extremely high pressure fuel coming out in that area....you need to hold a piece of paper around there to see where the fuel is leaking...it can cut right through your skin!

Download the 2006 KJ Service Manual here...some say you need the 2005 Service manual as well as one covers some items that the other leaves out and vice versa.

If you do not come right go to the CRD section at lostjeeps

Okay, so in the daylight now running I've figured out where the leak is. I'm not sure if there is a washer or some sort of seal that I'll need to replace. It's leaking right from the nut at the end of the fuel line going into what I believe are the injectors. Am I right?

Luckily it's not spraying, just dripping. But I'm sure it'll get worse if it's not taken care of. Chilton guide is worthless unless I'm changing a light bulb or something...

I think that is the fuel return line back to the tank...I have never worked in that area but I think that is a low pressure return line....the Service manual should have more information.

Maybe it needs a small Jubilee clip to clamp the hose tight?

The CRD section at lostjeeps should be able to help.

So, it turned out to be the High Pressure Supply Line into the fuel injector from the rail. The fuel injector itself on #3 was bad and has to be replaced and caused the line to back up. Unfortunately a $1000 job and in the shop now.

We have new injectors for $300 if you want to save some dough. GDE
