over fueling
 

Hi everyone, I am new to this site. I have a 1990 300e 24v problem I have is, it starts ok runs for about 15 mns then stops, I have to strip the injection system down and dry out the manifold,it fills with fuel till it blocks the manifold passage ways, .Idears please . Frank in the UK

Is there a vacuum line running from the fuel pressure regulator to the intake plenum? If so, see if this is full of fuel, which would indicate a ruptured diaphragm in the regulator = replace.

Thanks for the reply, that vacuum pipe is clear,I am getting good at striping the injection down to drain the air intakes, but am no closer to finding an answer:confused:
