Red fluid for gas gauge that doesn't fade

[tbirdman]

I'm looking for the red fluid for my 32 gas gauge that won't fade in direct sunlight. The stuff I got faded immediately after I put the top down.

[Guest bkazmer]

what is the fluid? I may be able to suggest a UV stable red pigment.

From what I have researched, I'm told it is Tetra bromo ethane. Also the dye that was used was Red Sudan which is now banned as a carcinogen.

tetra bromoethane is no regulatory gem either. Try pyrrolopyrrol, CAS (Chemical Abstracts) number 84632-65-5. Your friendly local paint place may know it as CI 254 red. Good UV stability and I think it will dissolve in tetra bromoethane.

Yes I know, I was warned not to drip any of it on anything. Of course I was warned after I had removed the gas gauge and dripped the liquid I'll give this suggestion to the gauge rebuilder.

Interesting is a local car restorer as given up on these and just put ATF in them and uses the old fill 'er up before you leave method.
