Can a Mercedes Benz Fuel injector be replaced?
Older mechanical injectors opened by fuel pressure alone and where easier to service, newer injectors are made of plastic, need an electronic pulse from the ECU to open and are better replaced than sending them out for service. A properly working injector will send a precise amount of atomized fuel into the induction system at a designated time.
How are the fuel injectors held in place?
There are four clips on it, two that you can see by the vacuum regulators, and two underneath. Pull the cover straight up and off. The fuel rail is held in place by four bolts and the rubber O-rings on the injectors, but there are a few things you will need to remove first to give you room to work.
Can a vacuum leak cause a fuel injector to leak?
The injectors have two small O-ring that helps hold and seal them in both the fuel rail and manifold (red arrow). If you are experiencing a vacuum leak it may be one of these O-rings. If you had a severely leaking injector it is not a bad idea to pull the plugs and turn the engine over a few times to get the gas out of the cylinder.
