So I was replacing the fuel filter the other day on a 2010 W221. When I reinserted the quick connect lines to the new fuel filter, the o-rings that were on the quick connect broke apart. Anyone knows how I could get this exact o-ring and replace the broken ones? Due to this I noticed that the fuel line wasn't able to hold pressure, so it always takes awhile to start up everytime I turn off the car and let it sit for awhile. I have attached a similar looking quick connect to the one I have and marked out the o-rings that I am talking about.
Doubt there is a Mercedes part# for those orings. But they will be expensive anyways.
When I needed orings for my lawnmower carburetor I went to Harbor freight and bought a nitrile oring assortment kit for $5. I had measured the oring before hand with my calipers so knew the size I needed. The kit ended up coming in handy when my floor jack started leaking fluid and replaced those orings.
