Here are the latest results of testing:
The two samples that I dyed with aniline dye have spent two weeks in the sun. The color didn't fade but there was some separation between the dye and fluid.
I was able to obtain a sample of Sudan Red dye, in a 1% solution. This 1% solution is used as a dye for biological samples. From what I've been able to find out Sudan Red may have been used in the original 30's fluid.
A sample dyed with the 1% Sudan Red had good color retention and no separation after two weeks in the sun.
My next test is to see if I can get a small sample of Sudan Red in powder form and use a little to dye the acetylene tetrabromide I purchased from King Gauge.
The 1% solution was not strong enough to color the acetylene tetrabromide I had, without greatly changing the density, which would have affected the fuel gauge accuracy.
Based on the two week sun test I should be able to dye the acetylene tetrabromide from King Gauge with Sudan Red powder and have a fuel gauge liquid that is red and doesn't fade.
I also tried using red food coloring, without good results.
I think I should ask BigKev to move this to a project forum....
Cheers....
