I have a 1985 500 SEL euro spec with about 185,000 miles on it and I noticed that one of my fuel lines is begining to crack. It's the black rubber hose located right next to the air intake and leading up to the fuel manifold. No leaks currently, but my mechanic told me that I should look into getting it replaced soon. The only issue is that he says you cannot get those lines anymore, and that it would have to be a custom job. Just wanted to know if anyone here has had any experience replacing this line and if there are any parts out there.

I was in a similar boat a few years back with the inlet and return line hoses. Did what several other member have done, and carefully cut crimped section of the hose barbs off, new high pressure line, and two quality clamps on each end. No issues since.

Before:


After:


You can probably use the same technique with great success on that hose next to the fuel distributor.

Gotcha, do you have the specs on the hose or should I search through the forums until I find it?

I used the CRP-Contitech Fuel Hose (PN: 916030000527) that I got off AutoHaus. It's a 7.5mm ID. One meter cost me less than $10.

I'm not sure if the OD of that hose is the same as the return/inlet. Might have to measure.

Thank you so much! I appreciate the information.

When I had similar issue, I took hose off and went to local hydraulic shop.
They do same thing except put new brass crimp on collar, just like oem.
Cost about $30. They will ask what the hose is for and spec the correct type.

I also had that problem last year. The same three solutions were suggested i.e. go to a hydraulic shop which should run $30-$40; make your own, or get oe from a mercedes dealer. All three work. My local hydraulic shop went out of business, trusted mechanic was in hospital (and I didn't want to mess with gasoline); so I opted for oe from a dealer. About $160 for the two. Am more than satisfied.

Bingo same here. I did new lines on my 560 a few years ago. And last year finally got around to doing my 420. Straight forward job. Just took some time to locally source some "fuel injected" rated hose, as normal fuel line is not designed for 80+psi use. So just keep that in mind.

You can cut the factory style crimp off carefully, then use an exacto blade to cut the hose so you can then remove it from the steel line barb. Then some nice "fuel system rated clamps", and your good to go. No more fire hazards lol
