My filled gauge lost some fluid, will it still work?
Your gauge will operate properly with low or no liquid fill.
What does the liquid do?
The liquid helps with vibration and keeps moisture and dirt out of the movement.
How do I refill my gauge?
You can fill the gauge with mineral oil, glycerin or silicone liquid. Before filling the gauge it is best to empty, rinse and dry the gauge first so you don't get two different fluids mixing (fluids with different viscosity will separate inside the case).
