Thats what I was thinking also. But why does a 240D get better fuel mileage than a 300D NA. Internal engine friction?

less displacement usually seems to equal better fuel economy, but youd think it would just be working harder.

What issues would you expect to see?

we ran an 8v 71 home to Minnesota from Albuquerque, NM on seven.
From what I recall, one injector stuck open, causing the engine to "run away" on us. that was a fun trip.
a truckshop unhooked that cylinder, we made it home just fine.

The fella who owned the rig did sell that bus(mci greyhound) to another guy outta Utah which flew in and I believe drove it home(I think he made it ok, never did hear any bad news, or good for that matter??)

I think that engine leaked enough oil everywhere that it was prolly just fine.:D

crimp
 

I had a line on my old SDL crack. I was in Charlotte near the indy that knew the car. He crimped the line to limit the flow, then bent it out of the way. We rigged up an empty oil bottle to catch the little bit of diesel that leaked out of the crimped line. I drove it 40 miles home and then 40 miles back. No apparent problems other than it ran slightly rougher. Any opinions if that would be acceptable for a longer time period?

Not hypothet. See thread for my tale

what happened to us

Here is a Mercedes diesel with the injection pump under the exhaust manifold and injection lines going between.

There is no issue with running a 603 with a cracked fuel line. There is no pressure developed in the cracked line and the fuel just runs down off the IP and onto the pavement.

Other than the lost fuel, there are no consequences of running the engine for 200 miles in this condition.

Had a fuel line break on a Sunday morning on I-10 near Jacksonville Fl. [1992 300D 2.5 turbo] went to Home Depot and got 20 feet of 3/16 plastic hose, slipped one end over the leaking fuel tube and ran the other end along the outside of the car and let it run back into the tank, leaving the fuel cap off, drove home to St Pete Beach Fl, about 300 miles. I didn't have the usual engine power, but I got home without making a mess in my engine compartment, or a fire. No damage to the motor.........Harlan

Thats not a bad quick fix! I'll remember that.
