Step-by-Step Installation Guide
Step 1: Prepare Your Workspace
Ensure your workspace is clean and organized. Disconnect the battery to prevent any electrical issues during the installation.
Step 2: Remove the Old Carburetor
Carefully remove the air cleaner and disconnect the throttle linkage, fuel line, and vacuum lines from the carburetor. Remove the carburetor from the intake manifold and clean the mounting surface.
Step 3: Install the Holley Sniper EFI System
Place the Holley Sniper EFI unit onto the intake manifold. Ensure that the gasket is in place to prevent any leaks. Secure the EFI system using the bolts provided in the kit.
Step 4: Connect the Fuel Lines
Install the fuel line fittings onto the Holley Sniper EFI. Connect the fuel line from the fuel pump to the EFI unit. Ensure all connections are tight and leak-free.
Step 5: Wiring the EFI System
Follow the wiring diagram provided in the Holley Sniper kit. Connect the power, ground, and signal wires to the appropriate terminals on the EFI unit. Ensure all connections are secure and insulated with electrical tape.
Step 6: Install the Oxygen Sensor
Locate a suitable location for the oxygen sensor in the exhaust system. Follow the manufacturer’s instructions for installation. This sensor is crucial for proper tuning and performance.
Step 7: Reconnect the Battery and Start the Engine
Reconnect the battery and turn the ignition key to the “on” position without starting the engine. This allows the fuel pump to prime the system. After a few seconds, start the engine and check for any leaks.
Step 8: Tuning the EFI System
Once the engine is running, use the Holley Sniper’s tuning features to adjust settings for optimal performance. Follow the instructions provided in the kit for detailed tuning guidance.
