Harbor Freight it is then for lunch today.

I'm starting to get my head around the vacuum system on this thing. From looking at the diagrams here I'll bet I pulled the fuel door unlock port free while messing with the hoses going into the trunk area.

Thanks for all the help, info, and answers on this forum. Diesel purge, italian tuneup, boost gauge, and controller. Tweaking my steering box adjustment was fun. It's been an interesting first month with the Benz. It wouldn't have happened without this site.
