There ought to be a law against using spring clips in places where they cannot be accessed. They probably put the vacuum lines on the turbo before they bolted the turbo to the exhaust.

The vacuum line with the problem is at the waste gate, below the turbo and only one hand can get down there. I can feel the 3 nibs of the clamp, I cannot see them as they are facing down and towards the firewall. Of course, using a pair of needlenose pliers means that I cannot 'feel' them catching any of the 3 prongs that need to be squeezed together.

Too late today for any more 'work'. So I get to think about it some. I wonder if I can turn the entire clamp up so that access will be better for pliers, without breaking off the brass nipple!

The new silicone lines will probably fit so snug that clips will not be needed. Lets hope so.
