2419679 XPI Fuel Injector Product Details
For Cummins ISX / ISX15 Diesel Engine | Direct Factory Supply | Full Cross-Reference Models in Stock
1. Product Overview
This model 2419679 XPI high-pressure common rail fuel injector is a brand new aftermarket replacement part independently developed and manufactured by our factory. It is precisely compatible with Cummins ISX, ISX15 series XPI fuel system diesel engines, and also fits Scania DC09, DC13, DC16 series engine platforms, can directly replace the original injector of the same specification.
This injector corresponds to multiple interchangeable cross-reference part numbers for the same XPI engine platform. All part numbers listed on this page are fully compatible and interchangeable, and all corresponding injectors are produced and stocked in our factory, available for direct purchase.
Developed and produced in strict accordance with original factory dimensions and performance standards, it effectively solves common engine faults such as poor fuel atomization, power drop, increased fuel consumption, difficult starting and black smoke under long-term high-load operation. It is widely used in maintenance and replacement of heavy-duty trucks, construction machinery, industrial generator sets, marine power and other equipment.
2. Core Product Advantages
① OEM-Spec Size, Direct Drop-In Replacement
The product dimensions, oil inlet interface and mounting positions fully match the original OEM parts. No modification to the fuel line or extra adjustment is required. It can directly replace damaged or failed original injectors, greatly reducing maintenance labor hours and equipment downtime for fleet and engineering users.
② Precision Calibration, Stable and Reliable Performance
Each injector undergoes high-precision flow calibration, high-pressure atomization testing and dynamic injection response testing on professional XPI test bench before delivery. The fuel injection pressure, fuel delivery volume, injection timing and atomization angle are fully consistent with original factory performance, ensuring uniform fuel supply for each cylinder, sufficient combustion, stable power output, and effectively reducing fuel consumption and exhaust emissions.
③ High-Quality Materials, Durable for Heavy Duty Conditions
Core internal precision components are made of high-strength wear-resistant, high-temperature resistant and corrosion-resistant alloy materials. Sealing elements and valve components are selected from high-end oil-resistant and high-pressure resistant materials, which can adapt to the long-term high-load and harsh working environment of heavy-duty diesel engines, greatly extending the service life of the product.
④ 100% Full Inspection Before Delivery, Consistent Bulk Quality
Different from loosely assembled parts on the market, all injectors from our factory are inspected one by one to eliminate unqualified products. The quality consistency of bulk orders is highly reliable, suitable for long-term stable stocking by auto parts distributors, truck repair workshops and fleet maintenance service providers.

4. Full-Process Quality Control System
To ensure the reliability of every product, we have established a complete quality management process covering the entire product life cycle:
Incoming Material Inspection: Core components are sampled for material composition, dimensional accuracy and hardness testing; unqualified raw materials are returned directly.
In-Process Inspection: Key dimensions are sampled and inspected at each machining stage to ensure machining accuracy meets the tolerance requirements of high-pressure common rail working conditions.
100% Finished Product Testing: After assembly, each injector undergoes seal test, high-pressure flow calibration, atomization effect test and injection cycle durability test one by one. Only products with qualified performance can enter the next procedure.
Final Inspection Before Shipment: Before delivery, the product appearance, model number and accessory integrity are double-checked to avoid wrong delivery or missing parts.

6. Installation & Usage Notes
It is recommended that the installation be operated by professional diesel engine maintenance technicians. Before installation, thoroughly clean the engine high-pressure fuel line and common rail pipe to avoid impurities entering the precision injector and causing internal damage.
Tighten the fixing nuts and fuel connectors according to the original factory specified torque during installation to avoid thread damage or high-pressure seal failure caused by excessive force.
After replacing the injector, it is recommended to perform injector coding and engine parameter matching to ensure the best operating condition and fuel injection accuracy of the engine.
Please use qualified diesel that meets the standards, and replace the fuel filter and water separator regularly. Inferior fuel with impurities will greatly shorten the service life of the precision XPI injector.
We recommend replacing the entire set of fuel injectors at the same time during engine overhaul. Due to differences in fuel output and atomization characteristics between genuine and aftermarket parts, mixed use is not recommended. Full set replacement helps avoid potential engine operation issues.
