Report: Fuel leak near high pressure pump, fuel lines at filter and pump
Mercedes-Benz E300 Problem
Average Mileage: 135,000 mi (85,000 mi - 185,000 mi)
Fuel leaks can develop around the high pressure fuel injection pump. The fuel lines around the fuel filter and the fuel pump also tend to leak.

I too had a fuel leak near the injector pump, I replaced all of the fuel lines and fix nothing. Then found it was leaking from the "Fuel Stop Valve" when I went to replace it I foumd it was only a bad O-ring.

fuel line seals leaking and allowing air into the system. Had to replace the lines and all is well.
Could smell diesel.
