NO, all of your red dye drained out of the glass. You will need to source more dye from Renner's Corner, as Sheldon stated or from Straight-Eight (is who I bought mine from before I knew about Dave Renner) https://straight-eight.com/product-c...rg-model-j-sj/. The only reason for the 1/8 copper line from the gas tank is to apply air pressure from the tank to the gauge to push the red fluid up the sight glass. As the pressure decreases (you burn fuel) the red fluid drops.
