Fuel indicator puck

When dealing with three kinds of fuel ie. gasoline, oil mixed gasoline and also diesel fuel my Dad and brother wanted something to indicate what type of fuel was in their fuelcans. Sharpie markers offcourse works but we thought that surely there must be a better way to do things.

That is why we created the Fuel indicator puck that not only locks on solid with a cable tie to any size fuel canister it also takes the guesswork out of finding the right fuel.

Hardware needed is a short pan head
