The Mitsubishi Eclipse GSX is a beloved vehicle among car enthusiasts, especially for those who appreciate tuning and performance upgrades. One of the essential upgrades for increasing power levels is enhancing the fuel system. This article will guide you through the steps and considerations necessary to upgrade your Eclipse GSX fuel system effectively.
Understanding the Fuel System
The fuel system in your Eclipse GSX is critical for delivering the right amount of fuel to the engine. It consists of various components, including the fuel pump, injectors, and fuel lines. Understanding how each part works will help you make informed decisions when upgrading.
- Fuel Pump: Responsible for delivering fuel from the tank to the engine.
- Fuel Injectors: Spray fuel into the engine for combustion.
- Fuel Lines: Transport fuel between components.
Why Upgrade Your Fuel System?
Upgrading your fuel system is essential if you plan to increase the power output of your Eclipse GSX. A stock fuel system may not provide enough fuel to support higher horsepower levels, leading to issues such as fuel starvation and engine knocking. Here are some reasons to consider an upgrade:
- Increased horsepower potential.
- Improved throttle response.
- Better fuel efficiency under high load.
Components Needed for an Upgrade
When upgrading your fuel system, several key components should be replaced or enhanced to ensure optimal performance. Below are the essential parts you will need:
- High-Performance Fuel Pump
- Upgraded Fuel Injectors
- Fuel Pressure Regulator
- Upgraded Fuel Lines
- Fuel Filter
High-Performance Fuel Pump
A high-performance fuel pump is crucial for supplying the necessary fuel flow and pressure to support increased power levels. Look for pumps that can handle higher pressure and flow rates than the stock unit.
Upgraded Fuel Injectors
Upgrading your fuel injectors ensures that your engine receives the correct amount of fuel for combustion. Choose injectors with a higher flow rate to match your performance goals.
Fuel Pressure Regulator
A fuel pressure regulator maintains consistent fuel pressure, ensuring optimal performance. An adjustable regulator allows you to fine-tune the fuel pressure according to your setup.
Upgraded Fuel Lines
Replacing stock fuel lines with larger diameter lines can help reduce fuel flow restrictions. Consider using stainless steel or high-quality rubber lines for durability.
Fuel Filter
A clean fuel filter is essential for protecting your injectors and engine. Upgrade to a high-flow fuel filter to ensure that your fuel system operates efficiently.
Installation Process
Installing the upgraded fuel system components requires careful attention to detail. Below are the general steps to follow:
- Gather all necessary tools and components.
- Disconnect the battery and relieve fuel system pressure.
- Remove the stock fuel pump and replace it with the high-performance pump.
- Install upgraded fuel injectors.
- Replace the fuel pressure regulator.
- Install new fuel lines and filter.
- Reconnect the battery and check for leaks.
Tuning Your Eclipse GSX
After upgrading the fuel system, tuning your Eclipse GSX is essential to ensure that the engine runs smoothly and efficiently. Tuning adjusts the air-fuel mixture, ignition timing, and other parameters to match the new fuel system.
- Use a wideband O2 sensor for accurate readings.
- Adjust the fuel map to accommodate new injectors.
- Consider a professional tune for best results.
Maintaining Your Upgraded Fuel System
Regular maintenance is crucial for ensuring the longevity and performance of your upgraded fuel system. Here are some maintenance tips:
- Replace the fuel filter regularly.
- Inspect fuel lines for leaks or wear.
- Monitor fuel pressure and adjust as needed.
Conclusion
Upgrading the fuel system in your Mitsubishi Eclipse GSX is a vital step towards achieving higher power levels. By carefully selecting and installing high-performance components, tuning your vehicle, and maintaining the system, you can enjoy increased performance and reliability. Happy tuning!
