Heavy Duty Truck, Liberation, Da Dongfeng Tianlong Flagship 1106010-E9300 Engine Oil Pump Assembly High Quality Fuel Pump & Parts

The Dongfeng 1106010-E9300 Fuel Transfer Pump Assembly is an original equipment (OE) mechanical fuel feed pump manufactured by Dongfeng Commercial Vehicle Co., Ltd. for its Euro VI (National VI) emission-compliant heavy-duty trucks. Designed as a core component of the low-pressure fuel system, this pump ensures reliable diesel delivery from the fuel tank to the high-pressure common rail pump — maintaining stable supply under all engine operating conditions.

Notably, on certain Dongfeng Longqing DDi11 platform configurations, this unit may be integrated or tandem-mounted with a hydraulic power steering pump, sharing a common drive shaft from the engine gear train. This dual-function layout makes it a critical multi-system power source that supports both fuel delivery and steering assist functions, increasing vehicle integration and space efficiency.
