The Mitsubishi Evo X is a beloved model among car enthusiasts, known for its performance and tuning potential. One of the essential upgrades for any Evo X owner looking to enhance performance is the fuel pump. In this article, we will guide you through the process of installing a DW 300c fuel pump in about three hours for an estimated cost of $180.
Why Upgrade Your Fuel Pump?
Upgrading the fuel pump is crucial for those who want to maximize their vehicle’s performance. The stock fuel pump may struggle to keep up with the demands of a tuned engine, especially when increasing horsepower. A high-performance fuel pump like the DW 300c offers several benefits:
- Increased Fuel Flow: Supports higher horsepower levels.
- Improved Reliability: Designed for high-performance applications.
- Cost-Effective: Affordable upgrade for significant gains.
Tools and Materials Needed
Before starting the installation, gather the necessary tools and materials:
- DW 300c Fuel Pump
- Fuel Pump Install Kit
- Socket Set
- Flathead Screwdriver
- Phillips Screwdriver
- Wire Cutters/Strippers
- Electrical Tape
- Safety Glasses
- Gloves
Installation Steps
Follow these steps to successfully install the DW 300c fuel pump in your Mitsubishi Evo X:
Step 1: Prepare Your Vehicle
Begin by ensuring your vehicle is parked on a flat surface. Turn off the ignition and disconnect the battery to avoid any electrical issues during installation. It’s also a good idea to relieve the fuel pressure in the system before proceeding.
Step 2: Access the Fuel Pump
To access the fuel pump, you’ll need to remove the rear seat. Locate the access panel under the seat and unscrew it. Carefully lift the panel to reveal the fuel pump assembly.
Step 3: Remove the Old Fuel Pump
Disconnect the electrical connector from the fuel pump. Use a flathead screwdriver to gently pry off the fuel line. Once disconnected, unscrew the retaining ring and carefully lift the fuel pump assembly out of the tank. Take note of how the old pump is connected for reference during installation.
Step 4: Install the DW 300c Fuel Pump
Take the DW 300c fuel pump and carefully install it into the fuel pump assembly. Ensure that it is seated correctly and secure it with the retaining ring. Reconnect the fuel line and the electrical connector, ensuring a snug fit to prevent leaks.
Step 5: Reassemble the Fuel Pump Assembly
Once the new fuel pump is installed, place the assembly back into the fuel tank. Make sure it is positioned correctly and secure it in place. Reinstall the access panel and the rear seat.
Step 6: Reconnect the Battery and Test
Reconnect the battery and turn the ignition to the ON position without starting the engine. This allows the fuel system to pressurize. Check for any leaks around the fuel pump area. If everything looks good, start the engine and monitor its performance.
Conclusion
Upgrading to a DW 300c fuel pump in your Mitsubishi Evo X is a straightforward process that can significantly enhance your vehicle’s performance. With the right tools and a little patience, you can complete the installation in about three hours for around $180. Enjoy the improved power and reliability that comes with this essential upgrade!
