294-3500 Fuel Injector — Cat C15 C18

This is a CAT Fuel Injector, a critical component responsible for precisely delivering fuel into the engine cylinders for combustion. Manufactured to exact OEM specifications, it ensures optimal fuel atomization and spray pattern for efficient power delivery and emissions control. A worn or faulty injector can cause rough idling, reduced engine power, increased fuel consumption, and black smoke from the exhaust.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial symptoms include rough idling, noticeable power loss, and increased fuel consumption. If ignored, the injector may fail to deliver fuel, leading to cylinder misfires and potential damage to pistons and valves. Continued operation risks significant engine performance degradation and costly repairs.

Installation Tip

Ensure the fuel system is properly bled of air after installation to prevent starting issues. Always use new copper washers and tighten injector hold-down bolts to the specified torque.

Service Note

Inspect the fuel lines, fuel filter, and fuel pump for any signs of contamination or wear when replacing fuel injectors.
