Detroit Diesel Series 60 Fuel System Diagram: Understanding the Components
The Detroit Diesel Series 60 fuel system is a crucial part of the engine, responsible for delivering the precise amount of fuel needed for combustion. Understanding the fuel system diagram is essential for diagnosing and troubleshooting engine problems. The system comprises several key components, including the fuel pump, injectors, fuel filter, and electronic control module (ECM).
Fuel System Components Explained
The Detroit Diesel Series 60 fuel system is a sophisticated system designed for efficient and reliable fuel delivery. Here’s a breakdown of its main components:
Fuel Pump
The fuel pump is responsible for drawing fuel from the fuel tank and delivering it to the rest of the fuel system. It’s a gear-type pump, known for its durability and ability to maintain consistent fuel pressure. The pressure is then regulated by a pressure regulator valve within the fuel pump housing.
Fuel Filter
The fuel filter removes contaminants from the fuel, protecting the injectors from damage and ensuring proper fuel flow. Regular fuel filter replacement is crucial for maintaining engine performance.

Injectors
The electronic unit injectors (EUI) precisely meter and inject fuel into the cylinders. Each injector is controlled by the ECM, allowing for precise control over fuel delivery based on engine load and speed. The EUI is one of the most complex parts of the system and is known to cause issues as engines age.
Electronic Control Module (ECM)
The ECM is the brain of the fuel system, monitoring various engine parameters and controlling the injectors. It receives input from sensors throughout the engine and adjusts fuel delivery accordingly. It uses data from engine speed, manifold pressure, and coolant temperature.
Fuel Lines
The fuel lines are the pipes that connect all the parts of the fuel system. Supply fuel lines are those that feed fuel to the engine, while return fuel lines carry excess fuel back to the fuel tank.
Common Issues and Troubleshooting
Several issues can arise within the Detroit Diesel Series 60 fuel system. These can include:
* **Low Fuel Pressure:** This may be caused by a failing fuel pump, clogged fuel filter, or leaking fuel lines.
* **Injector Problems:** Faulty injectors can lead to misfires, poor fuel economy, and reduced engine power.
* **ECM Malfunctions:** Issues with the ECM can disrupt fuel delivery and lead to a variety of performance problems.
Proper diagnostics using specialized tools are important to determine the root cause of issues.
Frequently Asked Questions
Here are some common questions about the Detroit Diesel Series 60 fuel system:
* **What type of fuel is required for a Detroit Diesel Series 60?**
It typically uses diesel fuel. Check your engine’s manual for the specific fuel requirements.
* **How often should I replace the fuel filter?**
Refer to your engine’s maintenance schedule, but generally, fuel filter replacement is recommended every 25,000 to 50,000 miles.
* **What are the symptoms of a failing fuel pump?**
Symptoms include difficulty starting, low power, stalling, and unusual engine noises.
* **Can I clean the fuel injectors myself?**
While some fuel injector cleaners are available, it’s generally best to have injectors professionally cleaned and tested.
* **Where can I find a Detroit Diesel Series 60 fuel system diagram?**
Diagrams are available in the Detroit Diesel service manuals or online through various technical resources.
Summary
The Detroit Diesel Series 60 fuel system is a precision-engineered system. A thorough understanding of its components and how they function together, combined with regular maintenance, is vital for maintaining peak engine performance and preventing costly repairs. Understanding the fuel system diagram is an important first step for anyone working on the engine.
