Looking for vacuum hose schematic for 91' 300sl
Hey,
I posted earlier asking about the location of where the vacuum hose from the fuel pressure regulator attaches to the vacuum source, which I think goes into the intake manifold and got no response. So with not getting any response am looking for a vacuum hose schematic for 91' 300sl so I can locate it myself. Can someone please help me! |

Frank,
Would not having this hose connected to the correct location be the cause of my hard start problem? MB300se65 |

As a general matter, no. If the vent of the FPR were to be connected to vacuum, there might be stumbling & stalling after start, and after the ECU had gone into closed loop. The cause of that would be low fuel pressure.
