5. Setup and Installation

This section outlines the general steps for installing the GOOFIT Fuel Pump Valve. Professional installation is recommended if you are unfamiliar with fuel system components.

1. Preparation: Ensure the vehicle is on a stable surface, the engine is off and cool, and the battery is disconnected. Have appropriate tools ready, including hose clamps, pliers, and a fuel-safe container for draining.
2. Locate Existing Petcock: Identify the current fuel petcock on your scooter or ATV. It is typically located near the fuel tank or carburetor.
3. Drain Fuel: Place a suitable container beneath the fuel lines. Carefully disconnect the fuel lines from the existing petcock and drain any remaining fuel from the lines and tank into the container.
4. Remove Old Petcock: Disconnect any mounting hardware securing the old petcock. Remove the old unit.
5. Install New Petcock: Position the GOOFIT Fuel Pump Valve (M088-007) in the same location as the old unit. Secure it using appropriate mounting hardware. Refer to Figure 3 for an example of an installed unit.
6. Connect Fuel Lines:
   • Connect the fuel inlet line from the fuel tank to the designated fuel inlet port on the new petcock.
   • Connect the fuel outlet line to the carburetor's fuel inlet.
   • Connect the vacuum hose from the engine's vacuum port to the vacuum pulsing hose/inlet port on the petcock.
   • If applicable, connect the secondary fuel inlet line.
   Ensure all connections are secure with hose clamps to prevent leaks.
7. Check for Leaks: Reconnect the battery. Turn the fuel supply on (if applicable) and inspect all connections for any fuel leaks before starting the engine.

6. Operating Instructions

The GOOFIT Fuel Pump Valve operates automatically based on engine vacuum. When the engine is running, it creates a vacuum that opens the valve, allowing fuel to flow to the carburetor. When the engine is off, the vacuum ceases, and the valve closes, preventing fuel flow.

• Normal Operation: Once installed correctly, the petcock will manage fuel flow automatically. No manual intervention is typically required during normal vehicle operation.
• Engine Start: When you start the engine, the vacuum created will open the petcock, allowing fuel to reach the carburetor.
• Engine Off: When the engine is turned off, the vacuum signal stops, and the petcock will close, preventing fuel from continuously flowing from the tank.

7. Maintenance

Regular inspection of the fuel pump valve and associated fuel lines can help ensure optimal performance and prevent issues.

• Visual Inspection: Periodically check the petcock and all connected hoses for signs of wear, cracks, leaks, or damage.
• Hose Clamps: Ensure all hose clamps are tight and secure. Replace any corroded or loose clamps.
• Fuel Filter: Consider inspecting or replacing your inline fuel filter as part of routine maintenance to prevent debris from reaching the petcock or carburetor.
• Cleaning: Keep the exterior of the petcock clean from dirt and debris. Avoid using harsh chemicals that could damage the material.
• Replacement: If the petcock shows signs of malfunction (e.g., fuel leaks, inconsistent fuel flow, or failure to shut off), it should be replaced promptly.

8. Troubleshooting

If you experience issues with your fuel system, consider the following troubleshooting steps:

• No Fuel Flow to Carburetor:
  • Check if the fuel tank has sufficient fuel.
  • Inspect the vacuum hose for cracks, kinks, or disconnections. A proper vacuum signal is essential for the petcock to open.
  • Verify that the fuel lines are not clogged or kinked.
  • Ensure the petcock is correctly installed and all ports are connected to the correct lines.
  • If the petcock is faulty, it may not open even with a vacuum signal.
• Fuel Leaks:
  • Immediately identify the source of the leak.
  • Check all hose connections and clamps for tightness.
  • Inspect the fuel lines and the petcock body for cracks or damage.
  • A faulty petcock diaphragm can cause internal leaks or failure to seal.
• Engine Stalling/Poor Performance:
  • Inconsistent fuel flow from a malfunctioning petcock can lead to engine performance issues.
  • Ensure the vacuum line is providing a consistent signal.
  • Rule out other fuel system components (carburetor, fuel filter, fuel pump if separate) as potential causes.

If troubleshooting steps do not resolve the issue, professional assistance may be required.
