Fuel smell in the engine compartment and visible leaking fuel on the lower hoses per the federal safety agency Campaign Number 18V837000. I previously complained about this in April 2025 (ID 11669847). Dealer inspected in April 2025 and replaced the lower hose, but I still would smell fuel. After a lot of my own troubleshooting over the last six months, I have determined that when the car has sat un-used for over 24 hours, the rubber fuel lines shrink just enough that the next time the fuel system is primed (pre-start routine when you unlock the car, or start the car), a small amount of fuel leaks out at the connection. If the car sits for weeks and then you start it up, fuel will visibly leak out of the rubber connection (I have video). Once the rubber line swells up again due to the fuel in the line, it will slow the leak. So, if you use the car daily, you will be less likely to notice a leak. If you use the car infrequently, you will be more likely to have a leak.

There is a fuel leak in the engine compartment. Mercedes replaced the high pressure fuel pump under warranty, but it's leaking somewhere else and it's no longer under warranty. It's an emissions issue(raw fuel leak) and a fire hazard. Checking the internet it seems this is very common problem w/o a common cure.

Major fuel leak from fuel hose feeding the high pressure fuel pump. We had it towed to a mercedes dealership to have it repaired. They reported that the c-class model sedans are experiencing the same issue. The mb metris has a c-class engine and the same components.the dealership is just replacing the hose for the fix but really has no explanation of why it is happening. The part is on backorder from germany due to so many experiencing this issue. I now am finding out that this has been a known issue but is being kept quiet. I have also seen many complaints on the mb metris forums about the same fuel leak issue.we noticed the problem when we started our car to let it warm up in the morning. The vehicle was stationary and the transmission was in the parked position. I came back outside and noticed a strong fuel smell. I looked under the car and noticed the fuel leak. The outside temperature was 26 degrees f at the time.
