Fuel Tank Sponge

What is the purpose of the sponge in the gas tank?

This "sponge" is used to prevent air pockets in the fuel. These air pockets are caused by equipment vibrations and can eventually lead to a condition called vaporlock. When the engine is vaporlocked, it will not be able to start.

Not all engines require the use of this sponge, and if your engine's fuel tank did not come equipped with one it cannot be added. If your engine does contain this sponge, it is very important that the fuel remain fresh. Stale fuel will cause the sponge to deteriorate and block fuel passages in the fuel system.
