Core Product Specifications
Crafted from premium corrosion-resistant and high-pressure-resistant materials (such as seamless steel or reinforced composite), this fuel supply tube boasts exceptional structural strength and leak-proof reliability. Its precision-formed shape and standardized fitting connections ensure tight, secure attachment to the fuel rail and injectors, eliminating the risk of fuel leakage even under extreme operating pressures (up to 200 bar) and temperature fluctuations (-40°C to 120°C). The inner tube surface is polished to minimize fuel flow resistance, maintaining stable fuel pressure and ensuring uniform distribution to each injector.
Beyond reliable fuel delivery, this tube resists degradation from fuel additives, moisture, and engine vibrations, extending the service life of the entire fuel system. Its lightweight design (only 0.085KG) and ergonomic routing adapt perfectly to the engine bay layout, allowing for quick, straightforward installation—no specialized tools or modifications are needed, making it suitable for both professional mechanics and DIY maintenance enthusiasts.
As a cost-effective and dependable maintenance solution, the 5258983 Injector Fuel Supply Tube is essential for regular engine servicing, fuel system overhauls, or replacement of cracked, corroded, or leaking tubes. It meets or exceeds industry performance standards, ensuring consistent fuel system operation, improved fuel efficiency, and enhanced overall reliability for your Cummins ISF2.8/ISF3.8-powered equipment.
