What/where exactly is the line/connector broken? Post a picture

 

Broken line is the green one, I removed it passed the connector that holds the two lines in place (both the metal and rubber hose) I am at a point now where there is some sort of metal valve similar to a tire valve.

 

I broke the black hose not the metal one that I pointed with the green arrow. It is at the point right now where there is some type of metal valve almost where I can't see it anymore because it starts to curve and get closer to the frame

 

This is the line I broke I will also attach a video.

 

The black hose delivers fuel under pressure to your engine. You can decide how important it is, if you want to fix it properly or attempt a bodge-up job.

You don't have the tools required to DIY the fuel line. Prepare yourself for the idea that you need to have it towed to a workshop.

Whatever happened to: "Hey guys, I'm planning to change my fuel filter. Should I buy the $10 pliers, or just use force?"

The entire line must be replaced. What is your full vin# ?

 

4JGAB75EX2A323489 and thank you for your help

 

Yes you are correct. And if I remember correctly, with an attitude.

 

So this post is almost two years old and I've had the vehicle stored, I am looking to get it fixed now and would appreciate any help going forward, I also thank you all who have contributed to this post. First my ML stalled and would not start up again, I replaced the fuel pump, and fuel filter but during the process I broke the "service only line" that runs to the engine, I stupidly did not purchase the $10 tool needed for this job, what parts exactly would I need to have this fixed? I know some have mentioned patching this line but not sure if that would be a good approach? The vehicle is an 02 ML500 and my next reply will be of the link to the video showing the line I am talking about and where it broke.

Thank You all for your help, I would really like to have my ML back on the road this summer.

 

 

Where did this break, under the left side doors?

Is this the feed line to fuel rail?

 

Yes sir

 

Here is the part number #95.

 

Thanks for the reply, also what other part would I need so that I can connect to the fuel service only line? Or does this fuel line come with the part necessary? I will circle the part I am referring to but it is where the loop line connects.

 

Thank you for your help

 

You are only going to get the line from the red arrow forward and nothing else.

 

What is the part number for the other part of the line that the loop end goes to?

 

The fuel filter an the feed line after the filter.

 

So I don’t need anything else?

 

Would I even need the service loop line? Or would I connect the line #95 directly to the service only port on the filter? is the line #95 long enough?

 

Would I even need the service loop line?

No. You don’t need the loop line.

As the note under the diagram explains, your 2002 ML is fitted with the larger filter, so it doesn’t require the extra line.

The original filter was shorter and fit directly onto the black fuel line. After they discontinued it, the simplest way to fit the longer filter was to run the loop.

Your ML has a shorter fuel line that connects directly to the fuel filter. When you correctly order part #95 in the diagram, they will send you the shorter line that matches your long filter.

You wasted your money buying the “service only” loop line. But that was 2 years ago.

(I am replying to the question for 43sqd in case he has given up on you.)

 

Dr. X, thank you for answering his question but he asked this question 11 hrs. ago.

Where in the world is there a requirement that I continuously sit by my desktop waiting to answer his next question?

 

Thanks to the help of everyone on the forum I was able to get the required parts in. It appears that everything matches up and requires no additional connectors to work as I was told. I should be having a friend do the work sometime this week and I was wondering if anyone had any info that would be helpful to him maybe a worksheet or any tips? Rocketman4321 mentioned on another post
“I have done the job, and it's nowhere near as bad as it sounds--really quite straightforward. (I chewed up the line on the first filter change--with the official tool--and it gave out on the second change.) I lifted the near side and loosened the far side and that worked well. It's really just 8 or 10 (big) bolts--there's no reason to minimize; just loosen them. Then jack the body with a big piece of wood to spread the load. You just need enough clearance to hop the old line out over the body mounts.

Parts.com has the line. Mine arrived with a connector rather different from the original, and it was missing the "keeper'. Fortunately it's a Ford Dorman connector and the local auto parts had the missing piece. (5/16" if I remember correctly). You could also try installing an aftermarket connector in the old line, but I think that takes a $30 tool, so you're almost at the cost of a new line.

And the job gives you time to contemplate why Mercedes has such an utterly idiotic filter location.” So if that’s all it is I will post back and give you guys some updates.

Thank You!

 

In this PDF posted by 43sqd in another post at the end it mentions a pressure hose and a clamp. Pressure Hose 119 589 04 63 00 and clamp 000 589 54 37 00. Is that the service valve where you release fuel pressure or is the hose and clamp another special set of tools I would need to replace the line. Also if I need any special MB tools please let me know! My friend has many clamps but not sure if it’s a special kind.

Thank You

 

Forget about the clamp, part numbers and the PDFs. You must order the part # below.

 

Yes that’s what I have. So if that’s all I need I’ll get going on it as soon as my friend can help. thanks

 

Here are all the procedures and understand that the body will have to be lifted.

 

Fuel line is replaced, new fuel filter and pump, new starter, CPS, and battery. Fuel pump isn’t making any noise. What should I do as my next diagnostic approach? Fuel pump relay K3 and Fuse 13 are ok. Also no fuel at fuel rail and red AAM light appears to be blinking which is a good sign.

Thanks for your help.

 

I also tested my 05 ML and when turned to position 1 the red light vlinks once every second for a good while and doesn’t stop. My 02 ML500 the light blinks a few times and stops. Could that indicate some sort of issue? Thanks

 

Check to see if you voltage at the fuse (hot side) then at the pump to eliminate bad wire or ground.

I12v at the fuse box and not at pump
Then wire harness is bad or bad ground or the out put on the fuse is bad.

If no 12 v on hot side fuse something is wrong there


12 v fuse and pump bad pump.

The fuse should be driver side kick panel the blocks are modular and span in and out could also be it is not set correctly or the sunroof drain leaked corroding it. Pull it out look it over note how it sets before removing.

 

Check to see if you voltage at the fuse (hot side) then at the pump to eliminate bad wire or ground.

How exactly should I do this with a test light? And at f13?

 

Test light would work but a multi meter s better. Pull fuse stick probe in the hot side of fuse do not be too forceful you do not want to bend the spring that clamps on the fuse lead then you need tho find a goof ground and ground black lead.

Can’t remember which fuse it is but it is left side f13 sounds right

 

Should I do this with the key turned? And just measure for voltage? Thank You

 

I had a CEL for C1140 Steering Angle Sensor, could that have anything to do with the non start and fuel pump not getting power? Is the steering angle sensor the das ring that goes around the key?
