Pilots need to inspect the fuel to make sure it’s the right type and that it is free from contaminants. That is where Sporty's Fuel Tester comes into play. This long, thin fuel tester is our most popular.  It fits all popular quick drain valves and includes a removable metal rod for recessed drains. Octane color codes are molded onto the transparent cylinder. A reversible (flathead/Phillips) screwdriver is mounted on the tip. Measures 8.5” long.
