Fuel Injection Service

At A & D Motors, we specialise in professional fuel injection services for heavy vehicles across Sydney. Whether you operate trucks, buses, plant machinery, or commercial diesel vehicles, maintaining a clean, precise, and efficient fuel injection system is essential for performance, fuel economy, and reliability.

Our experienced diesel mechanics are trained to diagnose, service, and repair common rail fuel injection systems, unit injectors, and older mechanical fuel systems, ensuring your heavy vehicle continues to operate smoothly and efficiently.

Why Fuel Injection Maintenance Is Critical

In modern diesel engines, fuel is delivered under extremely high pressure into the combustion chamber through precise injectors. Any dirt, carbon buildup, or wear in this system can lead to:

• Poor fuel economy

• Loss of power

• Engine misfires or knocking

• Increased exhaust smoke

• Hard starting or stalling

• Engine warning lights

• Higher emissions

For commercial vehicles and heavy-duty engines, these issues not only reduce performance but also affect compliance with emissions standards and can lead to costly downtime.

Regular fuel system servicing helps prevent these problems and extends the life of your engine.

Our Fuel Injection Services Include:

At A & D Motors, we offer a comprehensive range of fuel injection services for all heavy vehicles:

✅ Injector Testing and Cleaning

We use advanced diagnostic equipment to test your fuel injectors’ spray patterns, flow rates, and pressure delivery. If needed, we clean or replace faulty injectors to restore proper combustion.

✅ Fuel System Diagnostics

Our diesel technicians use scan tools and hands-on testing to locate faults within your fuel system, from the injectors and fuel pump to filters and lines.

✅ Common Rail Fuel System Repairs

We specialise in common rail systems used in most modern diesel engines. We can replace high-pressure pumps, fuel rails, sensors, and more.

✅ Fuel Filter Replacements

Blocked or contaminated fuel filters can lead to injector damage. We recommend regular filter changes based on your manufacturer’s schedule or operating conditions.

✅ Injector Resealing and Leak Repairs

Leaking injectors or seals can cause fuel loss, reduced engine performance, and even fire risks. We repair and reseal injector systems to factory standards.

✅ Emissions and DPF Compatibility

We ensure your injectors are delivering the correct fuel-air ratio to support proper DPF operation and meet emissions standards in NSW.
