Common Symptoms of a Failing Fuel Pump

Knowing the warning signs early can save you from being stranded on the trail. Here are the most common symptoms of a failing fuel pump on a 2019 Polaris Sportsman 570:

  1. Difficulty Starting: The engine cranks but takes multiple attempts to fire up. This is often the first sign of low fuel pressure.
  2. Stalling: The ATV stalls unexpectedly, especially at low speeds or when climbing hills, because the pump cannot maintain consistent pressure.
  3. Loss of Power: During acceleration, you notice a significant drop in power. The engine may feel like it is "starving" for fuel.
  4. Check Engine Light: The dashboard warning light may illuminate, especially if the ECU detects low fuel pressure or a fuel system fault.
  5. Fuel Leaks: Visible fuel dripping from the bottom of the ATV, often from cracked plastic nipples on the pump assembly or deteriorated fuel lines.
  6. Excessive Noise: A loud whining or humming sound from the fuel tank area, indicating the pump is working harder than normal or has worn bearings.

Replacement Options: OEM vs. Aftermarket

When the fuel pump fails, you have two main choices: buy an OEM replacement from Polaris, or choose an aftermarket pump. Aftermarket options are often more affordable and may offer better performance.

OEM replacement: The genuine Polaris fuel pump assembly for a 2019 Sportsman 570 typically costs between $137 and $180. It is a direct fit and guaranteed to work, but it may be more expensive and have a shorter warranty than some aftermarket alternatives.

Aftermarket options: Brands like KEMSO, OSIAS, All Balls, and Quantum Fuel Systems offer replacement pumps that meet or exceed OEM specifications. These pumps often use upgraded materials, such as Japanese armature motors and improved turbine impellers, to provide longer life and better performance.

Step-by-Step Fuel Pump Replacement Guide

Replacing the fuel pump on a 2019 Polaris Sportsman 570 is a job that most DIY mechanics can handle with basic tools. Here is a simplified guide based on the factory service manual:

Tools you will need:

  • Socket set and wrenches (metric and standard)
  • Screwdrivers (flathead and Phillips)
  • Fuel line disconnect tool (optional but helpful)
  • Shop towels or rags
  • Safety glasses and gloves
  • Torque wrench (for the retaining nut)

Step 1: Prepare the ATV

  • Park the ATV on a level surface and allow the engine to cool completely.
  • Disconnect the battery's negative cable to prevent electrical shorts or sparks.

Step 2: Access the Fuel Pump

  • Remove the seat and front cab (the plastic bodywork covering the fuel tank).
  • On some models, you may need to remove the air box for better access.

Step 3: Relieve Fuel Pressure

  • Start the engine and let it idle until it stalls from fuel starvation, or simply disconnect the fuel pump fuse and crank the engine for a few seconds.
  • Place a shop towel under the fuel line connector to catch any residual fuel.

Step 4: Disconnect Fuel Lines and Electrical Harness

  • Disconnect the fuel line quick-connect fitting by pressing the release tabs and pulling it apart.
  • Unplug the electrical connector from the top of the fuel pump assembly.

Step 5: Remove the Fuel Pump Assembly

  • Unbolt the fuel tank mounting bolts (usually two bolts) and slide the tank slightly to the right for access.
  • Unscrew the large retaining nut (PFA nut) on top of the fuel tank using a fuel pump service tool or a large strap wrench.
  • Carefully lift the old fuel pump assembly out of the tank. Be mindful of the float arm and the pre-filter strainer to avoid bending them.

Step 6: Install the New Fuel Pump

  • Clean the sealing surface on the fuel tank opening.
  • Place the new gasket onto the new fuel pump assembly.
  • Insert the new pump into the tank, ensuring the float arm is not bent or snagged.
  • Align the orientation marks on the pump flange and the fuel tank.
  • Thread the new retaining nut onto the tank and hand-tighten it. Then torque it to 70 ft-lbs (95 N·m) using the proper tool.

Step 7: Reconnect and Test

  • Reconnect the fuel line and electrical harness.
  • Reinstall the fuel tank bolts, air box, and body panels.
  • Reconnect the battery.
  • Prime the fuel system by cycling the ignition key on and off 6 times, waiting 3 seconds in the "on" position and 5 seconds in the "off" position.
  • Turn the key to start the engine. It should start within a few seconds.
  • Check for any fuel leaks around the pump and fuel line connections.

Maintenance Tips to Extend Fuel Pump Life

To keep your new fuel pump running for years, follow these simple maintenance practices:

  1. Use quality fuel: Choose high-octane, ethanol-free fuel when possible. Ethanol can attract moisture and cause corrosion inside the fuel system.
  2. Replace the fuel filter: It is recommended to replace the fuel filter at the same time as the fuel pump to ensure clean fuel flow.
  3. Keep the fuel tank full: Running the tank low frequently can cause the pump to overheat and suck in debris from the bottom of the tank.
  4. Store properly: If storing the ATV for more than 30 days, add a fuel stabilizer to prevent the fuel from degrading and gumming up the pump.

Conclusion

The 2019 Polaris Sportsman 570 fuel pump is a reliable component, but like any mechanical part, it will eventually wear out. Recognizing the symptoms early—such as hard starting, stalling, or loss of power—can help you avoid a breakdown on the trail. Replacing the pump with a high-quality aftermarket unit like the KEMSO 13012 is a cost-effective solution that delivers OEM-level performance backed by a lifetime warranty. Whether you choose to install it yourself or have a mechanic do it, using a quality replacement part ensures your Sportsman 570 stays reliable for many more miles of riding.
