It's a 1974 240d.

I looked at a schematic and it is listed as a overflow pipe.

In relation to the picture, the banjo fitting has a u shaped metal line attached which is about 1" long - u shaped and has an open end.

I'm trying to diagnose a run away engine - idle problem.

I took off the cover/housing for the governor and found the diaphragm is ripped.

So now I am going to start a new thread and see if anyone else has ventured into doing this.

I am currently unable to get the diaphragm out and wanted to know if I had to remove another housing.

Thanks,

Dwayne
