Kolor Kut Gasoline Gauging Paste, Made in U.S.A.
For checking the depth of Gasoline, Diesel, Biodiesel, Kerosene, and many other fuel oils in fuel tanks. The product is not so effective with Alcohols – because the alcohols evaporate off the dipping tape quickly returning the paste to its original state.
Applied to a rod / length of string with bottom weight and lowered to the bottom of a Gasoline tank, the paste changes colour where it comes into contact with Gasoline / Petrol, giving you a visual indication as to the depth of the Gasoline
