leaking diesel fuel injector

I noticed a drip coming from my 07 GC CRD and at first I thought it was my air conditioner. Then I got my oil change at the dealer and they said I had a fuel leak and wanted $150 to diagnose the problem. I told them no and I finally traced down the leak and it looks like the injector on cylinder 1 is leaking. Notice it's wet in the picture. At idle it's doing about 4-5 drips a second. From what I read is I may just need to replace the bolt and copper ring. I believe it's these...

I've never removed a fuel injector before. Any help would be appreciated, thanks

Why can't you just tighten up the connector?

tighten up the nut holding on the steel fuel line? I can try that. That sounds safer than replacing the copper washer and having to remove the injector. If the black rubber line is in the way, how can i remove it? It seems to swivel. I think it might snap on and off with a ball socket.

I have 90k miles on the Jeep. I've only had oil changes done recently and I replaced glow plug #6 which is on the other side of the engine.

The leak seems to be from the steel fuel line to injector. Tightening the nut should fix it. If not, it can help to loosen the other end of the steel fuel line and then finger tightening both ends while wigging the the fuel line a bit to help seat both ends. Then torque the nuts.

The plastic parts are not very forgiving on the injector

Either I fixed the leak and created a new one, or it was the O-Ring clip on the fuel return line the whole time. I broke the O-ring the spins around on the fuel return line. I read on the Sprinter forum that you press down hard on it and it'll snap and release the line. However it just snapped in half. I'm trying to find a part number for it but it looks like I need to replace the entire return fuel line now! Help?

This may help as well. Check product fit, etc but it's tracked down through merlintec's original post back in 09.

Thanks I read those threads previously. They point to replacing the entire $130 fuel line, when all I need is the O Ring. I'm trying to find a parts diagram for Mercedes, I may be able to get the $4 clip seperately from Mercedes since it looks like Europarts stocks it, I just don't know the part number.

I don't think there is a part number as I believe I read its all one unit?

I'm crossing my fingers it's 68005720AA and only $4. I found the part on the Sprinter parts page...
http://www.ourexcellentadventures.co...interParts.pdf
If it's not the right part I'm only out $4.

I finally fixed the problem. The o ring holding the leak line onto the injector was the cause of the leak. You cannot buy a new o ring. You need to replace the entire leak line, and its $150 online, or $250 at the dealer. I didn't want to spend that so I went to autozone and bought a piece of 3/8" ID fuel tubing and 2 hose clamps. I cut a 1 inch piece of fuel tubing and slid it over the plastic piece that connects to the injector and clamped it down on the top and bottom of the fuel tubing. No leaks! $4 fix where if I let the dealer do it I would have paid probably $800 for parts and labor.

here's a picture of the $4 fix I did. It's way cheaper than buying a whole new leak line.
