Due to a fuel leak we replace the o ring and seal on the injector pump.
after starting the car, fuel came out on top of the engine through the black air tubing that connects to the black tubing on top of the engine, which is removed now in order to get to the fuel injector pump.

Can you post a few pictures of what you're working on? It's been a number of years since I've looked at a Mercedes and 'high pressure pump' doesn't ring any bells. And I take it this is a diesel engine?
