60x Injector hard line broken, (by vibration) wtf? - Page 2 - PeachParts Mercedes-Benz Forum

I did this to my car (OM603.960), prior owner used zip ties and wire to hold hard lines in place.

The clips and pads are not exactly easy to install because they grab so tightly.

But once you do this you will be able to remove the line sets (1-3 and 4-6) as a unit if necessary.

Here are the parts for a 603 (h/t whunter)
Fuel Line Bracket 601-078-20-41-MBZ 2
Fuel Line Bracket 603-078-01-41-MBZ 6
Fuel Line Bracket 601-078-26-41-MBZ 4
Fuel Line Shim 601-078-04-86-MBZ 12

Here is a thread that has pics showing how to mount the clamps. Yes it says glow plugs but the subject came up in the thread.

The rubber pieces go between the hard line and the steel brackets. In some of the locations the pad needs to be trimmed to fit.

I had the same problem this summer. it was the #4 for me.

I found a complete set of used lines. including ALL the brackets. (here in the for sale forum!!!)

It turns out I was missing a few.

replacment is your best bet. New from the dealer they were $60-$70 each!

If you weld a fuel line, you pretty much are going to get scale on the inside. This will end up clogging the nozzle & necessitate R&R'ing or at least cleaning that nozzle. 60 bucks is a one time fix.

I have both tig & mig, they are not perfect in the garage. -corne-

Well I just had this same thing happen to me yesterday while I was on a road trip. #3 started squirting fuel from the nut. First thing I noticed was a Loss of power then a minute or two later I could smell diesel. I just wanted to ask if this could of caused any other damage I didnt drive the car much further maybe 4 or 5 miles after I found it. Parts are on their way just nervous hoping that's all that broke.

Only additional damage is environmental. No mechanical damage from lack of fuel to one or more injectors.

Hey Max would you go through the trouble of replacing all of the fuel lines & brackets? Contemplating replacing all of it.

Replace what's broken and move on with life. It's important to ensure that all of the plastic clips and rubber bumpers are in place on these engines. Missing plastic clips are a common problem and are likely the primary source of broken lines.

A pencil torch and thin brazing wire found at any hardware store will fix the crack. I have done this a number of times in the past. I still highly recommend getting a new line but for the time being it works. Better than a wobbly smelly drive!
Also yes, not having the lines clamped is absolutely why this happened and usually it happens pretty quickly. I have had three lines crack within a two week span before I realized the error in my ways.

Got to about 300k miles on my first 87 300d and three lines broke within a few hundred miles. Of course the clips were gone. I replace all of the lines and clips. And I'm going to do it on my new 87 now - preventative medicine. The clips on mine have been gone for years probably. Failure is predictable.
