I had the same problem with my MGA capillary tube. I soaked it
extensively in WD-40 and was finally able to get it to turn "freely
"on the tube. It however appears to be attached to the bulb in some
manner and won't slide up the tube.
If your are having trouble removing the sensor from the block, release
the gage from the dashboard and "straighten" out the capillary tube.
Have soneone turn the "free" gage as you turn the locking nut. This
will keep you from breaking the capillary tube. This method worked for
me. Good Luck.

I have some safety gauges gleaned from some A series motors.
Anyone have any ideas of how to get the nut off the bulb of
the capillary tube without destroying the tube? I have them
soaking in rust buster right now.
