131-3098 Fuel Injector — Cat 3408 3412

This is a high-pressure Fuel Injector responsible for precisely atomizing and delivering fuel into the engine cylinders at the correct time and volume. Manufactured to exact specifications, it ensures optimal combustion efficiency, unlike a clogged or leaking injector that causes rough idling, poor fuel economy, and increased emissions. Operators may notice black smoke from the exhaust, difficulty starting the engine, or a noticeable drop in power when a fuel injector fails.

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 of a failing fuel injector include rough engine idling, increased exhaust smoke (often black), and a noticeable decrease in engine power. If ignored, the injector may become completely blocked or leak excessively, leading to uneven cylinder operation, poor fuel economy, and potential damage to other engine components due to improper combustion. Continued operation risks significant internal engine damage from detonation or excessive heat.

Installation Tip

Ensure the injector seat in the cylinder head is perfectly clean and free of carbon deposits before installing the new injector. Overtightening the injector hold-down clamp can distort the injector body or damage the cylinder head threads.

Service Note

When replacing fuel injectors, it is crucial to inspect and replace fuel lines, seals, and the fuel filter to ensure optimal system performance and prevent contamination.
