Hi - I have common rail electronic fuel injection on a '73 450 SL engine which I have been trying to start for a while now. Does anyone know how this works please? The fuel comes into the rail via two small dome things (one after the other) with some sort of regulating bolts on top. I assume that these are for regulating the pressure in the rail. If I turn the ignition on, I get a 'wiz' from the fuel pump & pressure builds up in the fuel lines. For some reason no fuel comes out of the return pipe back to the tank, so I assume that no fuel is getting into the rail? Maybe the 'dome things' are adjusted wrongly? Does anyone have any experience with this type of system please?
