Do liquid filled fuel pressure gauges freeze in the winter?

autoX · 12-13-2001, 10:58 AM

Don't laugh at my question, but I am looking for a fuel pressure gauge for my brother's GT and was planning on buying a liquid filled model. But I am not sure if it will survive in temps well below zero!? Have any of you ever seen a liquid filled gauge freeze, or is the liquid some kind of an oil or something that doesn't freeze in sub-zero temps?

I am pretty sure that is oil in the gauges.

the only problem can be if you use an isolator and dont fill the line from the isolator to the gauge with a 50/50 antifreeze mix.
electronic ones dont need this but my old auto meterdoes.

and my car is outside right now in the snow,

Liquid filled gauges are typically filled with glycerin. No, it won't freeze.
