2017 Can-Am Outlander 570 Fuel Pump: Complete Guide to Symptoms, Replacement, and Maintenance

If you own a 2017 Can-Am Outlander 570, the fuel pump is one of the most critical components for keeping your ATV running reliably. When it fails, your machine simply won't start or will lose power on the trail. The good news is that replacing the fuel pump on this model is a manageable DIY job, and with proper maintenance, you can extend the life of your new pump significantly. This guide covers everything you need to know about the 2017 Can-Am Outlander 570 fuel pump, from spotting failure symptoms early to choosing the right replacement and installing it yourself.

How the Fuel Pump Works in Your 2017 Outlander 570

The fuel pump on your Can-Am Outlander 570 is an electric pump located inside the fuel tank. It delivers fuel from the tank to the engine at the correct pressure, ensuring your EFI system gets the fuel it needs for proper combustion . The pump is part of a complete module assembly that includes the fuel level sender, a filter sock, and the pressure regulator . This assembly sits inside the tank and is accessed from the top by removing the seat .

Common Symptoms of a Failing Fuel Pump

Recognizing the early signs of a failing fuel pump can save you from being stranded on the trail. Here are the most common symptoms to watch for:

1. Difficulty Starting
If your Outlander 570 cranks but takes longer than usual to start, or if it won't start at all, a weak fuel pump is often the culprit. The pump may not be building enough pressure to deliver fuel to the injectors .

2. Engine Sputtering or Surging
A failing pump can deliver inconsistent fuel flow, causing the engine to sputter, hesitate, or surge during acceleration. This is especially noticeable when climbing hills or carrying a load .

3. Loss of Power
If the pump can't maintain proper fuel pressure, the engine will feel sluggish and lack power, particularly under hard acceleration or at high RPMs .

4. Engine Stalling
A pump that is failing intermittently may cause the engine to stall unexpectedly, especially when running at low speeds or idling .

5. Loud Noise from the Fuel Tank
A healthy fuel pump produces a quiet hum. If you hear a loud, whining, or screeching noise coming from the fuel tank area, it indicates the pump is wearing out internally .

6. Poor Fuel Economy
A failing pump that runs inefficiently or continuously can cause a noticeable drop in miles per gallon .

7. Check Engine Light
On some Outlander 570 models, a weak fuel pump can trigger a check engine light with fault codes related to low fuel pressure, such as P0087 .

Diagnosing the Problem Before You Replace

Before you buy a new fuel pump, take a few minutes to rule out other issues. This saves time and money.

Step 1: Check the Fuses and Relay
Many riders have replaced a perfectly good pump only to find a blown fuse. Locate the fuel pump fuse and relay in your fuse box. Swap the relay with a similar one from the box to test it. If the engine starts or runs better, the relay was faulty .

Step 2: Listen for the Prime
Turn the key to the "ON" position (don't start the engine). You should hear the fuel pump hum for 2-3 seconds as it primes the system. If you hear nothing, the pump is not getting power or is dead .

Step 3: Perform a Fuel Pressure Test
This is the most definitive way to confirm a bad pump. You will need a fuel pressure test gauge that connects to the Schrader valve on the fuel rail. For the 2017 Outlander 570, the fuel pressure should be around 51 PSI (± 2 PSI) . If the pressure is significantly lower, fails to hold pressure, or drops off while the engine is running, the pump needs to be replaced .

Tools and Parts You Will Need for Replacement

Having everything ready before you start makes the job go smoothly. Here is what you will need:

  • New fuel pump assembly (complete module is recommended for reliability)
  • New fuel tank gasket or O-ring (often included with the pump assembly)
  • Socket set and wrenches
  • Screwdrivers (Phillips and flathead)
  • Fuel line disconnect tools (small sizes for quick-connect fittings)
  • A container for residual fuel
  • Safety glasses and nitrile gloves
  • A brass punch and mallet (or a fuel pump lock ring tool)
  • Clean rags

Step-by-Step Guide to Replacing the 2017 Can-Am Outlander 570 Fuel Pump

Follow these steps carefully. Always work in a well-ventilated area away from sparks or open flames. Keep a fire extinguisher nearby.

Step 1: Safety Preparation
Park the ATV on a level surface. Disconnect the negative battery terminal to prevent any accidental sparks . Drain as much fuel as possible from the tank using a siphon pump into an approved container. The tank should be as empty as possible for safe removal .

Step 2: Access the Fuel Pump
Remove the seat. On the Outlander 570, the fuel pump is located under the seat on top of the fuel tank. You will see a large circular plastic access plate or locking ring. Clean the area around it thoroughly to prevent dirt from falling into the tank .

Step 3: Disconnect Electrical and Fuel Lines
First, disconnect the electrical connector from the pump module. Then, use the fuel line disconnect tools to depress the quick-connect tabs on the fuel supply line. Have rags ready to catch any spilled fuel. If your model has a return line, disconnect that as well .

Step 4: Remove the Lock Ring and Old Pump
Use a brass punch and mallet (or a lock ring tool) to tap the large plastic locking ring counter-clockwise to loosen it. Do not use a steel hammer directly on the plastic ring, as it can crack. Once the ring is loose, lift it off. Carefully lift the entire pump and level sender assembly out of the tank. Be mindful of the fuel level float arm—do not bend it .

Step 5: Clean the Tank
Before installing the new pump, use a flashlight to inspect the inside of the fuel tank. You will likely see some sediment or debris at the bottom. Use a lint-free rag to wipe it clean. A clean tank is one of the best ways to ensure your new pump lasts .

Step 6: Install the New Fuel Pump Assembly
Compare the new pump assembly with the old one to make sure they match. Install the new tank sealing gasket or O-ring onto the tank opening. Carefully lower the new pump assembly into the tank, aligning the tabs with the notches in the tank opening. Make sure the float arm moves freely. Hand-tighten the lock ring, then use your tool to give it a final snug turn. Do not overtighten, as this can crack the plastic ring .

Step 7: Reconnect and Test
Reconnect the fuel lines until you hear a distinct "click" when they are fully seated. Reconnect the electrical connector. Reconnect the negative battery terminal. Turn the key to the "ON" position and listen for the new pump's prime sound. It should be strong and consistent. Cycle the key on and off 2-3 times to build full pressure. Inspect for any fuel leaks around the lock ring and connections. If all is dry, start the engine. It may crank slightly longer as the system builds pressure for the first time. Let it idle and check for leaks again .

Maintenance Tips to Prolong Fuel Pump Life

Taking care of your fuel system will help your new pump last for years. Here are the most important tips:

Keep the Tank Above a Quarter Full
The fuel pump is cooled and lubricated by the gasoline it sits in. Running the tank consistently low causes the pump to overheat and work harder, significantly shortening its lifespan. Make it a habit to refuel before the gauge drops below the quarter mark .

Use Clean, High-Quality Fuel
Contaminants and water in gasoline can damage the pump's internal components. Purchase fuel from reputable stations. If your ATV will be stored for more than 30 days, use a fuel stabilizer to prevent varnish and gum formation .

Replace the In-Line Fuel Filter
The Can-Am Outlander 570 has an external, in-line fuel filter. While the in-tank pump has a coarse sock filter, this main filter catches smaller particles. A clogged filter forces the pump to work harder. Replace this filter at the intervals specified in your owner's manual .

Maintain Proper Electrical System Voltage
A weak battery or failing stator can cause low system voltage. The fuel pump motor runs slower under low voltage, reducing performance and causing it to overheat. Keep your battery terminals clean and your charging system in good health .

Choosing the Right Replacement Fuel Pump

When it is time to replace the fuel pump on your 2017 Outlander 570, you have several options. The OEM part number for this model is 709000461 . A complete pump assembly is usually the most reliable choice, as it includes the pump, strainer sock, locking ring, and seals .
