This is exactly what am experiencing on my 2016 C300. Even my car mechanic couldn't figure out why the fuel smell is happening occasionally. Thank you!
Hello! You mentioned that the faulty hose has been updated. Do you know know whether later iterations of the M274 has had this part fitted as standard? At least i havent been able to find anyone with a car older than 2017 complaining about this. I´ve got a C300E 2020 model (european hybrid model) and on cold mornings I can feel a very slight sense of fuel smell (most people would probably not notice it). Ive heard about the leaking fuel line issue before, so i was wondering if i might have the same problem. For me the smell seems to go away after about 30-120 seconds of just idling (before i drive away). Wondering if what im expiriencing is just a result of some unburnt fuel in the exaust system that results from the rich fuel mixture during a cold start in low temps - from my understanding its not uncommon to get a bit of a fuel smell because of this.

I am having this problem,, its why I am here :) thank you for the video
Great job. Very clear
I have this same problem with my GLC 300 - question is is it okay if I leave it? Is it causing any problems?
So do I. I also have a GLC 300
Can you please tell me the part number for this hose
Would this be covered by warranty?

How much does it cost to fix it?
That will depend on the location and type of shop you go to. Approximately $200-350
You can do it yourself part is like $50-70
Where are you located? I would love to bring my GLC300 in for the same thing
Taped the bottom to the new line and pulled it from the top. It was kind of ez, just had to rotate it into position before clamping
Having a bad line, will it cause low performance from the engine?
Depends on the severity of the leak. A considerable leak can lead to loss of fuel pressure which can impact system performance.
What was the part name / number for the redesigned updated hose ?
Fuel Hose,To High-Pressure Pump,
Part number 2740703500
or you can also get 2740700181 .
It should cost about $15 dollars from the dealer.
Good Luck!
