ALDA Service -- 85 300SD -- Differant!?

[71inka02]

OK -- taking tomorrow off...actually took today off too - but regardless....

Car has been feeling a bit sluggish, so for tomorrow, I'm planning a 'banjo bolt' clean on my 85 SD...along with some other maintenance stuff -- Just pulled car in the garage, and lifted the hood - thought I'd go ahead and get that part out of the way, in an effort to make the best use of my time!

The line from the 'banjo bolt' goes directly to the ALDA instead of a 'switch over valve' that I'm familiar with on my 83 300D --- The device pictured is supposed to be the 'switch over valve'....isn't it? So, can anyone tell what I've got....?

No abusive harrassment on my ignorance, please.

Thanks in advance for help, direction and information...
