OK I can tell you that the astris marked tube is the main gas line and the ? marked tube is the equalizer tube from the Accumulator to the fuel damper, it can leak as well.

Well From what I have learned about these Euro Cars, I'd replace all the gas line rubber connections and lines before a smog test then do a pre-test to determine IF you have a leak in those evap controls(1983 MAY NOT have had the same emissions added that my 1984 did as my car was imported in 1988). Could be also that your car will have a N/A type functional controls...meaning that it not testable. State says that the 1984 is not able to be tested and that is true, BUT...my car was federalized in 1988 and that crap was added to it.

Easy to tell. If you have an EGR valve on the driver's side manifold(little hat looking valve with a metal tube elbowing in front to the manifold and another one from the rear of the EGR valve that crosses over behund the valve cover and disappears into the intake manifold.

A picture of the driver's side exhaust manifold would tell us that story. I kinda think you don't have an EGR valve.

I wish you were closer, I'd just come over and jack the car up on that side, block it up, crawl under and tighten the connections. Then we'd see if that helped or not. It really looks like those hoses have never been replaced. I've been under mine more times since August than I'd like to admit. Under, over and inside under the Air metering plenum and the fuel distributor replacing the vacuum lines. Feel like I know this car intimately now.
