Thanks guys. That's how I did it the first time. Either then, or more likely when I loosened it to remove the line a piece of the copper tube is now stuck in the gauge. Really stuck. I guess if I ever have to remove it again I will take it loose at the block.

The good news is I no longer dread installing and removing the gauge cluster. I am actually getting good at it after 3 times in and out. I read about Alvin and others misadventures in re-doing these old trucks and even though I tell myself I am not going to make that same mistake I seem to end up doing the same things more than once.
