How to bleed fuel lines on a 190e 2.6L?
Anyone knows how to safely bleed the fuel lines on a 190e 2.6L (1993). The idea I have (!) is to energize the fuel pump while the engine is cold then crack the lines open. Am I righ, If so, how do you energize the pump on these cars?

There is no need to bleed the system on a gas engine car. The system bleeds itself after a few seconds of ignition voltage.
In a diesel, the volume of fluid put through the barrel on each stroke is minimal, thus without bleeding you would run down two or three batteries before enough fuel works its way to the injectors to provide total liquid, thus adequate pressure to overcome the hundreds of pounds of pressure in the cylinder. A gas engine does not have any of these problems. To begin with the pump is electric and starts building pressure and providing volume immediately upon receiving voltage. Secondly, once the injector opens, it is injecting fuel into an intake runner that is not under pressure as is a diesel cylinder. Hope this helps, |

There is no procedure in the MB shop manual to bleed the fuel system of an M103.
You'll probably flood a cylinder or two if you jump the fuel pump. Sixto 95 S420 91 300SE 87 300SDL 83 300SD |
