What Is the Yamaha New OEM Fuel Pump ASY 6E5-24410-03-00?

The ASY 6E5-24410-03-00 is Yamaha’s genuine replacement fuel pump, engineered specifically for select Yamaha engines. As an OEM part, it’s designed, tested, and manufactured by Yamaha to match the exact specifications of the original pump in your vehicle. This isn’t a generic aftermarket part—every detail, from materials to performance metrics, aligns with Yamaha’s quality standards.

Key Functions of This Fuel Pump

A fuel pump’s primary role is to draw fuel from the tank and deliver it to the engine’s combustion chambers at the correct pressure and flow rate. The ASY 6E5-24410-03-00 does this reliably, ensuring:

  • ​Consistent fuel pressure: Prevents engine hesitation or stalling under load.

  • ​Accurate flow rate: Matches the engine’s demand for fuel during acceleration, idling, or cruising.

  • ​Durability: Built to withstand vibrations, temperature fluctuations, and fuel contaminants common in real-world use.

Which Yamaha Models Use This Pump?

This fuel pump is compatible with several Yamaha engines, including:

  • ​Yamaha YZ-F Series ATVs: Popular in off-road and utility applications.

  • ​Yamaha Grizzly Utility Vehicles: Known for their ruggedness and workhorse capabilities.

  • ​Certain Yamaha Motorcycle Models: Specifically older or mid-range models where fuel system reliability is critical.

    To confirm compatibility, always cross-reference your vehicle’s VIN or engine code with Yamaha’s parts catalog—this ensures you’re getting the right fit.

Why Choose the Yamaha OEM Fuel Pump Over Aftermarket Alternatives?

When your fuel pump fails, you might be tempted to save money with an aftermarket part. However, for critical components like the fuel system, OEM parts often outperform generics in the long run. Here’s why the ASY 6E5-24410-03-00 is worth the investment:

1. Precision Engineering for Perfect Fit

Aftermarket pumps may claim “universal fit,” but slight variations in size, connector types, or internal calibration can lead to leaks, poor pressure, or even damage to your fuel tank. Yamaha’s OEM pump is molded to match your vehicle’s fuel system exactly—no modifications needed.

2. Consistent Performance Under Stress

Yamaha tests its OEM pumps under extreme conditions: high temperatures, vibration, and prolonged use. Aftermarket parts often cut corners on materials (e.g., using lower-grade plastics or weaker motors), which can cause premature failure when you need the pump most—like during a trail ride or workday.

3. Warranty Protection and Support

Yamaha backs its OEM parts with a warranty, typically 12–24 months. If the pump fails due to manufacturing defects, you’re covered. Most aftermarket brands offer shorter warranties or none at all, leaving you to handle repairs if the part fails.

4. Preserving Your Vehicle’s Resale Value

Using OEM parts maintains your vehicle’s integrity. Buyers and appraisers recognize that original components mean the bike or ATV was maintained properly, which boosts resale value. Aftermarket parts can raise questions about whether corners were cut during repairs.

Technical Specifications: What Makes This Pump Tick?

Understanding the technical details of the ASY 6E5-24410-03-00 helps you appreciate its design and troubleshoot issues. Here are the key specs:

Voltage and Power Requirements

This pump operates at ​12 volts, standard for most Yamaha vehicles. It draws minimal current (around 5–7 amps) to reduce strain on your electrical system while delivering consistent pressure.

Flow Rate and Pressure

The pump delivers a flow rate of approximately ​1.2 liters per minute​ at 39.2 psi (2.7 bar). This balance ensures the engine gets enough fuel without overwhelming the fuel lines or carburetor/injector system.

Materials and Construction

  • ​Housing: Made from high-strength nylon reinforced with glass fibers, resisting cracks from fuel expansion or physical impact.

  • ​Impeller: A precision-machined plastic component that pushes fuel through the pump. Its smooth edges minimize friction and wear.

  • ​Seals: Viton®-based O-rings prevent fuel leaks and resist degradation from ethanol-blended fuels, a common issue with cheaper parts.

Compatibility with Fuel Types

The ASY 6E5-24410-03-00 works with regular unleaded gasoline and ethanol blends up to E10 (10% ethanol). For regions using higher ethanol content (E15+), Yamaha recommends checking compatibility, as extended exposure to ethanol can degrade some plastics over time.

Step-by-Step Installation: Replacing Your Fuel Pump

If your vehicle is showing signs of fuel pump failure (more on that later), replacing the ASY 6E5-24410-03-00 is a manageable DIY task with basic tools. Here’s how to do it safely:

Tools and Materials Needed

  • Socket set (including 8mm, 10mm, and flathead screwdrivers)

  • Fuel line disconnect tool (or needle-nose pliers)

  • Rags or shop towels (to catch spills)

  • Safety glasses and gloves

  • New fuel filter (recommended to replace at the same time)

  • Container for old fuel (if draining the tank)

Safety First

  • ​Disconnect the battery: Prevent accidental sparks by removing the negative terminal.

  • ​Relieve fuel pressure: Locate the fuel pump relay (check your service manual) and unplug it. Start the engine and let it stall—this burns off residual pressure.

  • ​Work in a well-ventilated area: Fuel fumes are flammable; avoid open flames or sparks.

Installation Steps

  1. ​Access the Fuel Pump: Depending on your model, the pump may be mounted inside the fuel tank or along the frame rail. For tank-mounted pumps, drain the tank (or siphon out enough fuel to access the pump). For frame-mounted pumps, remove any protective covers.

  2. ​Disconnect Fuel Lines: Use the disconnect tool to separate the inlet (from the tank) and outlet (to the carburetor/injector) lines. Cap the lines immediately to prevent dirt from entering.

  3. ​Remove Electrical Connectors: Unplug the pump’s wiring harness—note the orientation to ensure proper reconnection.

  4. ​Install the New Pump: Align the new ASY 6E5-24410-03-00 with the mounting bracket, pressing it into place until it clicks. Reconnect the fuel lines and wiring harness.

  5. ​Reassemble and Test: Replace covers, reconnect the battery, and turn the key to “ON” (without starting) for 10 seconds—this primes the pump. Start the engine and check for leaks around the connections.

Troubleshooting: When Does Your Fuel Pump Need Replacement?

The ASY 6E5-24410-03-00 doesn’t fail without warning. Here are common symptoms of a failing pump:

1. Hard Starting or No Start

If the engine cranks but won’t fire, the pump may not be delivering enough fuel. Test this by turning the key to “ON” (not start)—you should hear a faint whirring sound from the pump priming. No sound? The pump or its relay may be faulty.

2. Sputtering at High Speeds

As you accelerate, the engine may hesitate or “bog down.” This happens when the pump can’t keep up with the engine’s increased fuel demand.

3. Loss of Power Under Load

Towing, climbing hills, or carrying heavy loads requires more fuel. If the engine loses power in these situations, the pump may be worn out.

4. Fuel Leaks or Whining Noises

Visible fuel leaks around the pump or a high-pitched whine indicate internal wear—either the impeller is damaged, or seals have failed.

Maintenance Tips to Extend the Life of Your Fuel Pump

Preventive maintenance is key to avoiding costly repairs. Here’s how to keep your ASY 6E5-24410-03-00 (and your fuel system) healthy:

1. Use Clean Fuel

Contaminants like dirt, rust, or water in the fuel tank can clog the pump’s inlet filter or damage the impeller. Always fill up at reputable stations and use a fuel stabilizer if storing your vehicle for extended periods.

2. Replace the Fuel Filter Regularly

The fuel filter traps debris before it reaches the pump. Yamaha recommends replacing it every 50–100 hours of use or annually—whichever comes first. A clogged filter forces the pump to work harder, shortening its lifespan.

3. Inspect Electrical Connections

Corrosion or loose wires can disrupt the pump’s power supply. Check the connectors periodically and clean them with electrical contact cleaner if needed.

4. Avoid Running on Empty

Running your vehicle with low fuel levels can overheat the pump—it relies on fuel to stay cool. Keep the tank at least a quarter full to maintain proper cooling.

Where to Buy the Yamaha OEM Fuel Pump ASY 6E5-24410-03-00

To ensure you’re getting a genuine Yamaha part, purchase from authorized dealers or Yamaha’s official online store. Avoid third-party marketplaces where counterfeits are common. Signs of a fake pump include:

  • Poorly molded housing with rough edges.

  • Missing or incorrect part numbers on the label.

  • No warranty documentation or Yamaha branding on packaging.

Pricing for the ASY 6E5-24410-03-00 typically ranges from 120, depending on the retailer and region. While this is more than aftermarket options (70), the reliability and warranty make it a better long-term investment.
