Preparation Steps
Before starting the installation, ensure you have all tools and materials ready. Make sure you work in a well-ventilated area and wear safety gear.
1. Disconnect the Battery
Begin by disconnecting the negative terminal of the battery to prevent any electrical shorts during installation.
2. Relieve Fuel System Pressure
To relieve fuel system pressure, locate the fuel pump relay in the fuse box. Start the engine and remove the relay while the engine is running. This will stall the engine and relieve pressure.
Removing the Old Fuel System
Next, you will need to remove the existing fuel system components to make way for the new Flex-a-Lite system.
3. Remove the Fuel Lines
Using the fuel line disconnect tool, carefully disconnect the fuel lines from the fuel rail. Be prepared for some fuel spillage; use shop towels to clean up any spills.
4. Remove the Fuel Rail
Unbolt and remove the fuel rail from the engine. Ensure all injectors are disconnected before removing the rail completely.
Installing the Flex-a-Lite E85 Fuel System
With the old system removed, you can now install the new Flex-a-Lite E85 fuel system.
5. Install the New Fuel Rail
Position the new fuel rail onto the engine and secure it with the provided bolts. Ensure that the injectors are properly seated in their respective ports.
6. Connect the Fuel Lines
Reconnect the fuel lines to the new fuel rail. Ensure that all connections are tight to prevent leaks.
Electrical Connections
Electrical connections are crucial for the proper functioning of the Flex-a-Lite E85 fuel system.
7. Connect the Fuel Pump Wiring
Follow the wiring diagram provided in the Flex-a-Lite kit to connect the fuel pump wiring. Use wire cutters and strippers to prepare the wires, and secure connections with electrical tape.
8. Reconnect the Battery
Once all electrical connections are made, reconnect the negative terminal of the battery.
Final Steps
After installation, it’s important to check for leaks and ensure everything is functioning properly.
9. Check for Fuel Leaks
Turn the ignition to the “ON” position without starting the engine to pressurize the fuel system. Inspect all connections for leaks.
10. Start the Engine
Start the engine and let it idle for a few minutes. Monitor the fuel system for any irregularities or leaks.
