The conventional oil pump oil supply system matched with the saddle-shaped oil tank is generally divided into two types, one type adopts a fuel pump to be arranged in a main oil chamber, fuel in an auxiliary oil chamber is sucked into the main oil chamber by utilizing a siphon principle, the fuel pump sucks oil from the main oil chamber and supplies oil to an engine, and when the oil consumption of a vehicle is too high, the fuel pump cannot meet the requirement of the fuel flow required by the vehicle. The other type is that two fuel pumps are respectively arranged in a main oil chamber and an auxiliary oil chamber of a saddle-shaped oil tank, the two fuel pumps both adopt a double-siphon structure, fuel in the auxiliary oil chamber is siphoned into an oil storage barrel of the fuel pump positioned in the main oil chamber, fuel in the main oil chamber is siphoned into the oil storage barrel of the fuel pump positioned in the auxiliary oil chamber, and meanwhile the two fuel pumps respectively suck oil from the oil chambers in which the two fuel pumps are respectively positioned and supply oil to an engine, so that the oil consumption requirement of the engine is jointly met.
