Cleaning overboost lines, clarifications - PeachParts Mercedes-Benz Forum

OK ... so I dove right in. And created a mess. First of all, when I lightly gripped the line from the manifold to the overboost relay, it snapped! So I guess that needed to be replaced, not cleaned. No problem ... I bought some line as a safeguard. Then I couldn't get the screws out of the retaining clips on the connecting tube. Is there some secret to doing this or am I just inept?

They are totally corroded solid and there's no way to get a good grip on them to get any leverage with the screw driver. I ended up having to remove the overboost relay and eventually cut off the connecting hose and clip. I do not have replacements for the clips and rubber connectors. They didn't have any in stock at the dealership, which I found out after about 20 minutes of trying to explain to the guy who works there what I needed. He looked at me like I was speaking Spanish when I mentioned things like the ALDA and overboost relay. I had to draw him a DIAGRAM. LOL.
Anyhow, now I have no line between the relay and the manifold, and I'm sure the line between the ALDA and relay is equally brittle and crudded. So, here are the questions:
1) I could only get the hose for the manifold to relay ... they did not have the hose for the ALDA to relay in stock. Can the first hose be used for both applications? As far as I can see, the only difference is a red line on the side of the latter. I have a meter of the plain line.
2) Is there a trick to getting those screws out or do I have to completely demolish all the clamps and just replace them?
3) The nipple on the manifold is very cruddy. Should I stick a pipe cleaner in there, or just squirt carb cleaner in the hole?
How do I manage to turn the simplest of things into meltdown?

Here are some photos of my huge mess. At left is dirty line and new line ... yuck. Middle shows the devil screw brackets. Right is the end of the hose off the manifold ... cruddy.
