Recently purchased a running 75 with 1.8 l-jet. While replacing the vacuum hoses noticed my egr has a port on the back of the valve. Can't see where it is on the pelican diagram. Either I'm missing something obvious or migh this be a later bus motor or something weird. Any help appreciated. Will try to add a picture it's on the lower right on the back of the valveClick to view attachment
There is no hose on it at the moment
Thanks for any help
