Other Fuel System Pump problems of the 2016 Mercedes Benz Metris

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.

There is a strong gas smell inside and outside the van when first started in the mornings. The smell is to the point that you have to drive the first few miles with the windows down. I took the van to hendrick motors in charlotte, nc where it was purchased new to have it checked at 40,250 miles. They offered to fix the problem for $603 and I feel this is a design flaw that should be fixed at no charge. The estimate they gave me states, "replace long rubber fuel feed line and clamps to high pressure fuel pump (rubber fuel feed line to high pressure fuel pump porous causing concern).

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.
