High Pressure Fuel Injection Pump OE 16700T156B for Dongfeng Captain Light Trucks

This genuine high pressure fuel injection pump with OE number 16700T156B is factory original common rail fuel system component exclusively matched for Dongfeng Captain DFAC light commercial diesel trucks. It pressurizes diesel fuel and delivers stable high-pressure fuel to fuel injectors to realize precise fuel injection control. The pump housing adopts high-strength cast aluminum alloy. Internal precision plunger assembly undergoes strict grinding treatment, ensuring stable pressure output and low internal leakage. Built-in pressure control valve accurately regulates rail pressure to optimize fuel atomization and combustion. Standard mounting flange and fuel pipe interfaces perfectly match original engine pipeline layout for direct bolt-on replacement. This fuel pump strictly passes DFAC OEM continuous pressure cycling test, high-low temperature durability test and fuel tightness test. Authorized third-party fuel system inspection verifies mounting dimension, flow parameters and electrical specifications fully consistent with factory original assemblies, widely used as replacement spare parts for insufficient power, unstable idling and fuel leakage failed pumps on urban delivery Dongfeng Captain fleets.

01

Precision Plunger Assembly, Accurate Pressure Regulation, Low Internal Fuel Leakage

This OE 16700T156B high pressure fuel injection pump adopts ultra-precision ground plunger pair to maintain stable high-pressure fuel output during long-time engine operation. Integrated pressure control solenoid valve dynamically adjusts common rail pressure according to engine working conditions, improving fuel atomization efficiency and lowering fuel consumption. Multiple sealing structures effectively prevent internal and external diesel leakage. Flange mounting hole position, fuel inlet/outlet ports and electrical connector strictly follow original Dongfeng Captain engine design specifications. No pipeline modification or gasket custom processing needed during replacement. Optimized internal flow path reduces pressure fluctuation, stabilizing engine idle speed and enhancing power output under heavy load.

Unstable Rail Pressure Causes Rough Idle, Poor Precision Leads To Power Loss, Easy Fuel Leakage

Light truck diesel maintenance technicians often face common faults of inferior aftermarket fuel pumps: inaccurate pressure control causes engine shaking and unstable idle; low-precision plunger leads to insufficient power and higher fuel consumption; simple sealing structures easily produce diesel leakage and pollute engine compartment. This genuine DFAC OEM high pressure fuel pump eliminates these hidden risks: precision components guarantee stable pressure; reliable sealing prevents fuel leakage, reducing engine fuel system overhaul frequency for Dongfeng Captain delivery fleets.

DFAC OEM Captain Fuel System Standard, Multi-Round Pressure & Durability Lab Testing

As core fuel system spare part of Dongfeng Captain DFAC light truck diesel engine, this high pressure fuel injection pump fully complies with Dongfeng Automobile commercial vehicle fuel component production quality standards. Every finished pump completes three mandatory durability laboratory tests: long-cycle pressure reciprocating simulation test, -40℃~+120℃ high-low temperature durability test, long-time static and dynamic fuel tightness test, maintaining stable working performance under urban frequent start-stop, bumpy road and all-weather transportation environments. Anti-counterfeit label and clear OEM part number are printed on original packaging for authenticity verification. All flange outline size, pipeline thread and electrical connector definition strictly follow original vehicle engineering drawings, zero assembly mismatch after replacement for all matching Dongfeng Captain light truck models.
