300sd 123 diesel fuel line leak?

Question

ok i unpluged one of the rubber fuel return line, because it's squirting out fuel, and found a crack in the line, so i reattach it (so i can go and buy a new line) but it's leaking out of control, it won't stop, i'm wasting expensive diesel, how can i stop the leak, fuel shut off switch?

help!

i don't know what i'm doing, this is my first diesel

Answer 1

Jay's right, but why the thumbs down? You really can't shorten the cigar shaped return hose. You can use a regular piece of fuel line for a temporary repair.

Answer 2

I answered your question in the maintenance and repairs section.

What I'll tell you here is that a 300SD is not a 123 chassis.  Depending on the year, the 300SD name was used on the 116, 126 or a 140 chassis.  The 123 chassis had the 300D and 300D turbo ( essentially the same engine as found in the 116 and 126 chassis 300SD's, they all used variations of the M617 5 cylinder diesel ).

Answer 3

smiply cut the line clean and attach.If to short,vaccum line will work until you can get the right lines.Order biodiesel rated,they last longer.

Answer 4

It would be best to take it to the nearest Mercedes dealer to have it fixed. Trying to do it yourself could cost you more in in lost fuel than a dealership repair.

The same logic applies to online advice about how to fix it yourself, it's hard to tell who knows what.
