How to Install an E85 Fuel System Kit in an E15 Car

by Admin | April 16, 2024

If you’re a car enthusiast or simply looking to enhance your vehicle’s performance, converting to E85 fuel can be a game-changer. E85, a blend of 85% ethanol and 15% gasoline offers several benefits, including increased horsepower, reduced emissions, and potentially lower fuel costs. In this guide, we’ll walk you through the process of installing an E85 carburetor conversion kit in your E15 car.

Understanding E85 Fuel

Before diving into the installation steps, let’s briefly understand what E85 fuel is and why it’s gaining popularity:

  • E85 Composition: E85 consists of 85% ethanol (derived from corn or sugarcane) and 15% gasoline. Its high ethanol content makes it a renewable and environmentally friendly alternative to regular gasoline.

Benefits of E85:

  • Higher Octane: E85 has a higher octane rating than regular gasoline, which can improve engine performance.
  • Cooler Combustion: E85 burns cooler, reducing the risk of engine knocking.
  • Lower Carbon Footprint: Ethanol is a renewable resource, and using E85 contributes less to greenhouse gas emissions.

Choosing the Right E85 Carburetor Conversion Kit

Before purchasing a conversion kit, ensure that your car is compatible with E85. Most modern vehicles can handle E85, but it’s essential to check your car’s specifications. Now, let’s proceed with the installation:

Installation Steps

Step 1: Gather Necessary Tools and Materials

  • E85 carburetor conversion kit (such as the Radium Parts kit)
  • Basic hand tools (wrenches, screwdrivers, pliers)
  • Fuel line cutter
  • Multimeter
  • Wire connectors
  • Safety glasses and gloves

Step 2: Locate the Fuel Line

Identify the fuel line in your car. It usually runs from the fuel tank to the engine. You’ll need to install the E85 sensor in-line with this fuel line.

Step 3: Install the E85 Sensor

  • Cut the fuel line using the fuel line cutter.
  • Insert the E85 sensor into the cut section of the fuel line.
  • Secure the sensor using hose clamps.

Step 4: Wiring Connections

  • Connect the E85 sensor wires to the corresponding wires near the fuel injectors.
  • Use wire connectors to ensure a secure connection.
  • Check the wiring using a multimeter.

Step 5: Install the Piggyback ECU

  • Mount the piggyback ECU (included in the conversion kit) in a suitable location.
  • Connect the ECU to the E85 sensor and the car’s existing wiring.
  • Follow the manufacturer’s instructions for proper wiring.

Step 6: Test and Start the Engine

  • Turn on the ignition and check for any fuel leaks.
  • Start the engine and let it run for a few minutes.
  • Monitor the E85 sensor readings on the piggyback ECU.

Final Checks

  • Ensure that all connections are secure.
  • Refill the fuel tank with E85.
  • Drive the car and observe its performance.

Congratulations! You’ve successfully installed an E85 carburetor conversion kit in your E15 car. Enjoy the benefits of running on E85, and remember to adjust your fuel map if necessary. Happy driving! 🚗💨
