4. Setup and Installation

Follow these general steps for installing the WIX Filters 33002 In-Line Fuel Filter. Always refer to your vehicle's specific service manual for detailed instructions and safety precautions.

4.1. Tools and Materials Required:

• New WIX Filters 33002 Fuel Filter
• Fuel line clamps (if not reusing existing ones)
• Pliers or fuel line clamp tool
• Catch pan for fuel
• Rags or absorbent towels
• Safety glasses and gloves

4.2. Installation Steps:

1. Prepare the Vehicle: Park the vehicle on a level surface. Ensure the engine is off and has cooled down. Disconnect the negative terminal of the vehicle's battery.
2. Relieve Fuel Pressure: Consult your vehicle's service manual for the correct procedure to relieve fuel system pressure. This typically involves disabling the fuel pump and running the engine until it stalls, or using a specialized tool.
3. Locate the Fuel Filter: Identify the existing in-line fuel filter. It is usually located along the fuel line, often near the fuel tank or in the engine bay.
4. Position Catch Pan: Place a suitable catch pan directly underneath the fuel filter to collect any spilled fuel.
5. Remove Old Filter: Loosen the clamps securing the fuel lines to the old filter. Carefully disconnect the fuel lines from both ends of the filter. Be prepared for some fuel spillage.
6. Install New Filter: Observe the flow direction arrow on the new WIX 33002 filter. Connect the fuel lines to the new filter, ensuring the flow arrow points towards the engine. Secure the fuel lines with new or existing clamps, ensuring a tight, leak-free connection.
7. Check Connections: Double-check all connections for tightness and proper seating.
8. Reconnect Battery: Reconnect the negative terminal of the vehicle's battery.
9. Prime Fuel System & Check for Leaks: Turn the ignition key to the 'ON' position (without starting the engine) for a few seconds to allow the fuel pump to prime the system. Repeat this a few times. Then, start the engine and carefully inspect all fuel line connections around the new filter for any signs of leaks. Address any leaks immediately before driving the vehicle.
