You avoid the costs and frustrations of a premature failure, improper engine operation, and multiple installations. It protects the investment in your vehicle.
- Warranty Coverage: A genuine Yamaha OEM part typically comes with a manufacturer's warranty, providing peace of mind that is rarely matched by aftermarket suppliers.
Symptoms of a Failing Fuel Pump Assembly
Recognizing the signs of a failing fuel pump can prevent you from being stranded. If you experience any of the following with a vehicle that uses the 6E5-24410-03-00 assembly, the fuel pump should be a primary suspect:
- Engine Won't Start or Crank: The most obvious sign. If the fuel pump cannot build pressure, the engine will crank but not fire. Listen for a faint humming sound from the fuel tank area when you turn the ignition to the "ON" position (before starting). No sound may indicate a dead pump, relay, or fuse.
- Sputtering or Loss of Power at High Speed/RPM: As demand for fuel increases, a weak pump cannot keep up, causing the engine to stumble, surge, or lose power as if it's running out of gas.
- Engine Hesitation or Stalling Under Load: When you accelerate quickly or go up an incline, the engine may bog down or stall if the fuel pump is not delivering adequate volume.
- Unusual Noise from the Fuel Tank: A loud whining, grinding, or buzzing noise from the pump is a clear indicator of internal wear or impending failure.
- Decreased Fuel Economy: A pump operating outside its specified parameters can disrupt the optimal air-fuel mixture, leading to wasted fuel.
Step-by-Step Guide to Replacing the Fuel Pump Assembly
Replacing the fuel pump assembly is a manageable task for a knowledgeable DIYer with the right tools. Always work in a well-ventilated area, away from sparks or open flames. Relieve the fuel system pressure before beginning and disconnect the battery.
Tools and Materials Needed: New OEM Fuel Pump Assembly 6E5-24410-03-00, socket set, screwdrivers, fuel line disconnect tools, shop towels, a new fuel tank gasket (if required), and a safe container for any residual fuel.
- Preparation: Ensure the vehicle is on a level, stable surface. Disconnect the negative battery cable. For ATVs, you may need to raise the rear or remove the seat and body panels to access the fuel tank. For WaveRunners, access is typically under the seat or a deck plate.
- Access the Fuel Pump: The fuel pump is mounted on top of the fuel tank. You will need to remove any trim, seats, or covers to expose the access panel or the top of the tank itself. There will be several hoses and an electrical connector leading to the pump module.
- Disconnect Fuel Lines and Wiring: Carefully label or take a photo of the hose routing. Use a fuel line disconnect tool to safely detach the feed and return lines—pulling on them can damage the fittings. Unplug the electrical connector.
- Remove the Pump Assembly: The pump is held in the tank by a large locking ring or several screws. Use the appropriate tool (often a spanner wrench or a hammer and punch) to loosen the locking ring by turning it counter-clockwise. Once loose, carefully lift the entire assembly out of the tank. Be mindful of the fuel level float arm.
- Transfer Components (If Necessary): In some cases, you may need to transfer the fuel level sending unit (float) from your old assembly to the new one, though the OEM assembly often comes complete. Follow the instructions provided with the new part.
- Install the New OEM Assembly: Clean the sealing surface on the fuel tank. Carefully lower the new OEM fuel pump assembly 6E5-24410-03-00 into the tank, ensuring the float arm moves freely and is not bent. Align the tabs or marks correctly. Secure it by tightening the locking ring or screws to the specified torque.
- Reconnect Everything: Reattach the fuel lines, ensuring each "clicks" securely into place. Reconnect the electrical connector. Double-check all connections against your photo.
- Final Steps: Reinstall any access panels, trim, or seats. Reconnect the battery cable. Turn the ignition to "ON" for a few seconds (without starting) to allow the new pump to prime and pressurize the system. Listen for its normal operational hum. Check for any fuel leaks. Start the engine and let it idle, checking for leaks again and ensuring it runs smoothly.
Troubleshooting Common Issues Post-Installation
Even with a perfect installation, it's good to know how to diagnose related issues:
- Engine Still Won't Start: Verify that the pump is getting power. Check the main fuse and the fuel pump relay. Listen for the pump priming. If there's no power, the issue may be in the relay, wiring, or ECU.
- Fuel Leak: Immediately turn off the engine. Recheck the sealing ring on the pump assembly and the connections of the quick-connect fuel lines. A damaged O-ring or a fuel line not fully seated is the most common cause.
- Incorrect Fuel Gauge Reading: If you transferred the old fuel level sender, it may be faulty or misadjusted. Ensure the float arm is installed correctly and moves without obstruction.
Maintenance Tips to Extend Fuel Pump Life
Protecting your new investment is simple:
- Keep Your Fuel Tank Clean: Avoid running the vehicle on extremely low fuel. The fuel in the tank cools the pump, and running it low consistently can lead to overheating. Sediment at the bottom of the tank can also be drawn into the pump.
- Use Clean, Quality Fuel: Contaminated or old gasoline can clog the inlet strainer and cause the pump to work harder, leading to premature failure.
- Replace Fuel Filters: Adhere to the manufacturer's recommended service intervals for the in-line fuel filter. A clogged filter forces the pump to strain against high pressure.
