[diesel_mercedes] Re: 1981 240D stick vacuum problems

 

My 1981 240D standard has been giving ne fits with a stumbling and
stalling problem - as well as what I thought was a brake booster gone
bad. WRONG! At least I now think the problem is a vacuum leak. My
pump puts out about 18 inches of vacuum, which is about right at 4000
feet elevation. I have looked for a couple of years for a vacuum
diagram for my specific car. No luck anywhere. Anyone out there with
help??

I think that I have about 10 inches with everything hooked up. I think
the vacuum goes so low that the fuel shutoff starts to shut down the
engine and it starts to stumble. I have a Mityvac and so can test
stuff. The problem is not knowing where anything goes. There is a
green/yellow (I think) line into the "Tee" off the main line from pump
to the brake booster. I has been broken off and the "Tee plugged. I
really need a vacuum diagram in order to track the leak. Somebody help?

Nate,

I forget where I bought it, either eBay or Craig's List.
The intent was to scan it, to make it available
Currently, I have no scanner ready to go.
