Fuel Gauge Liquid - King Seeley Hydrostatic Gauge

Posted by 32model901 On 2011/2/6 8:50:06

Has anyone run across a supplier of the fluid for King Seeley Hydrostatic Fuel Gauges that doesn't turn clear after exposure to light?

All the sources I've tried have the same result - the liquid goes from red to light amber after 3 - 6 months, faster if exposed to light.

Some background on the fluid used originally:

Chemical Name - acetylene tetrabromide also called 1,1,2,2-tetrabromoethane

Specific gravity- 2.95 to 2.96

Color - red

Original literature called for it to be dyed with 'Durant' scarlet dye.

The modern replacement liquid sold by the vendors has a tendency to lose its color after some time.http://www.classicandexotic.com/store/p-300-king-seeley-fuel-gauge-red-fluid.aspx

Any Chemists out there that can suggest an available substitute?

I've included some repair tips for this type gauge I ran across.
