Hello, Board. I have a 1987 300E and I am in a serious crappy situation, I was doing my white Faced gauges that I bought from ebay, while I was pulling the cluster I mistakenly pulled out the Vacuum hose for my economy gauge wayy down past the cluster(probably from the beginning connection). The trouble is, that I dont know where that connection is. Someone please help me.

I believe it goes through a firewall grommet and to a check valve on the otherside of the firewall above the brake booster.

Thanks a lot, I looked under my hood and there it was. You saved me a lot of time and headache.

Thanks again
