In many cases the engine setting alters as the fuel level in the tank runs down; i.e. the mixture "leans out". This effect can be cured by installing this small hopper tank (as well known as surge tank), which guarantees a reliable, constant flow of fuel, especially during aerobatics.
The hopper tank should be installed at the height of the carburettor; it is supplied complete with accessories and holder.
