Factors Effecting this growth The automobile production in China will keep steady increase in the next 5 years. China has a big Vehicle Population, the fuel pump’s repair and replacement is also a big market. The export trade of fuel pump keeps continuous high-rate growth The local OEM and joint venture have more opportunities to choose local supplier’s fuel pump in the EFI system.

2)Brushless pumps also require less energy to operate. 3)The energy saving comes in two areas: a) One is that losses are eliminated from the brush-to-commutator interface. b)The other is that it’s possible to run the computer-controlled brushless pump just enough to provide fuel to the engine. 5) In return less systems, eliminating the recirculation fuel reduces a source of heat to the fuel tank. This means the evaporative emissions system can be smaller. 6) Improves the pump's robustness to fuel and reduces flow variation
