From what I've been able to find out the red dye originally used in the gauge liquid, acetylene tetra-bromide is no longer used.

The substitute dye, fades upon exposure to light. Acetylene tetra-bromide that is not dyed is light amber in color.

Every source for this liquid that I've tried fades.

The recent source I found claims their product does not fade.

I have a sample on order and will test it to see if their claim is true, results will be posted.
