OM606 diesel fountain. New return lines. Any help appreciated
 

E300 with 180,000 miles. Pools of fuel in wells. Has to be be return lines. Cut em put em on. Proud and happy I was. Started the car and was waiting for self bleeding to happen. Mistake #2. While I was basking in the joy of a job well done the car was shooting a spray of fuel 3 feet in the air. What s mess. The fuel looks like it is coming from the center of the nut for the fuel line. Pulses with the engine. I could not get a good look without getting a face of fuel. Now it's on my shirt, pants and hair but I was able to keep it out of my eyes. I did undo and retighten the fuel line nut. I don't think it's the return lines in that it sprays with a lot of force from the nut line connection.Mistake #1 was thinking the plastic tubing going to the turbo was flexible. Broken pipes I can live with. Spraying diesel might be a problem with neighbors as work are smells like a truck stop. Any help is greatly appreciated.

Post some pictures of whats going on so we can see what needs remedying.

Sounds like the hard line at the injector is cracked or leaking. Could be a loose nut but not probable if you did not remove it.

Thanks
 

I did retighten nut to fuel line connection. As far as photos are concerned this is one case where words are better. to get a photo camera would be coated in fuel and the spray would not be all that visible. I can do photos of the area that the fuel shoots out of. It's between the nut and the fuel line. Dead center. If you follow the fuel line to the injector it's shooting out of the clearence between the nut and the line. Thanks again

It sounds like post #3 is your problem. If clips that hold hard lines are absent they move around causing weakness. Then you may have bumped or bent it further during the return line work. A common area for that failure is where the the top of the nut touches the hard line. Maybe a photo with engine off with the area circled could be helpful also.

Cracked hard line due to improper support, been there done that. Those clips are vital for proper operation of the engine.
