Product Description
1129600KFA High Pressure Fuel Pipe is a precision seamless steel pipeline for JAC JE493ZLQ6M common rail diesel engine. It connects high-pressure fuel pump and fuel injector, delivering diesel under ultra-high common rail pressure to guarantee accurate fuel injection quantity and timing. This aftermarket pipe solves unstable rail pressure, fuel leakage and power fluctuation caused by metal fatigue cracking, damaged cone sealing surface and thread deformation under long-term vibration and high-pressure impact. Stable fuel conveyance maintains good combustion efficiency and avoids black smoke and engine derating for JAC light trucks equipped with JE493ZLQ6M engine used for urban logistics and inter-town short haulage.
Product Advantages Made of high-pressure seamless alloy steel tube with special forming treatment. Precision cold bending retains structural strength without internal residual stress. The double-cone sealing end is finely machined to achieve reliable sealing under common rail high pressure. Every finished pipe undergoes hydraulic burst test and air tightness inspection before packing, OEM pipe routing shape, length and connector specification for direct replacement.
