A 2 inch long Tennessee grasshopper is exactly the right size to plug up the fuel tank pickup tube on a 47 Mercury convertible, the first car I ever bought, in 1962. The car would run almost exactly a mile before the fuel in the carburetor float bowl and the fuel line ran out. Wait 30 minutes, and the engine would restart and run another mile. Two fuel pumps, an inline fuel filter, and a carburetor got changed before I found the real problem!
