You’re geared up, the trail is calling, and you hit the ignition on your Can-Am Outlander… only to be met with a weak crank, a sputter, or worse, complete silence. We’ve all been there. That sinking feeling when your trusty machine won’t fire up can ruin a perfect day of riding. More often than not, the culprit is hiding right inside your fuel tank.
I promise, you’re in the right place. This isn’t just another generic parts page. This is your complete, hands-on guide from a fellow rider and mechanic. We’re going to break down everything you need to know about your 2018 can am outlander 570 fuel pump, from diagnosing the problem like a pro to replacing it yourself.
In this guide, you’ll learn how to spot the early warning signs of a failing pump, perform definitive diagnostic tests, and follow a safe, step-by-step replacement process. Let’s get that Outlander roaring back to life.
What a Healthy Fuel Pump Does for Your Outlander 570
Think of your fuel pump as the heart of your ATV’s fuel system. Its one critical job is to pull gasoline from the tank and send it under high pressure to the engine’s fuel injectors.
When it’s working correctly, it delivers a steady, precise stream of fuel, allowing your engine to run smoothly, efficiently, and powerfully. For your 2018 Outlander 570, this means crisp throttle response on the trail and reliable starts every time.
A healthy pump is the foundation of a reliable machine. Without correct fuel pressure, even a perfectly good engine will struggle, leaving you stranded.
Telltale Signs: Common Problems with a 2018 Can-Am Outlander 570 Fuel Pump
A fuel pump rarely dies without warning. It usually sends out distress signals first. Learning to recognize these symptoms can save you from being stuck deep in the woods. This is one of the most important parts of any 2018 can am outlander 570 fuel pump guide.
Hard Starting or a Complete No-Start
This is the most obvious symptom. If the pump is too weak to build adequate pressure when you turn the key, the injectors won’t have enough fuel to start the engine. You might hear it crank and crank, but it just won’t catch and fire up.
Sputtering, Stalling, and Hesitation
Is your Outlander running rough, especially under load? If it sputters when you climb a hill or stalls when you come to a stop, it’s likely starving for fuel. An inconsistent pump can’t keep up with the engine’s demands, causing these frustrating and dangerous issues.
Noticeable Loss of Power
If your once-snappy 570 now feels sluggish and weak, a failing fuel pump could be the cause. Low fuel pressure creates a “lean” condition, meaning there’s too much air and not enough fuel in the combustion chamber. This robs your engine of power, especially at higher RPMs.
A Loud Whining or Buzzing Noise
When you first turn the key to the “on” position (without starting the engine), you should hear a faint, two-second hum from the fuel tank area. This is the pump priming. If that hum has turned into a loud, high-pitched whine, it’s a classic sign the electric motor inside the pump is straining and on its last legs.
How to Diagnose Your 2018 Can-Am Outlander 570 Fuel Pump
Before you start ordering parts, let’s confirm the fuel pump is actually the problem. Proper diagnosis saves you time, money, and headaches. Safety first: always work in a well-ventilated area, have a Class B fire extinguisher nearby, and wear safety glasses. Fuel is highly flammable.
The Simple “Key-On” Listening Test
This is your first and easiest check. Find a quiet spot, put your ear near the fuel tank, and turn the ignition key to the “on” position. You should hear that distinct 2-3 second hum or buzz as the pump primes the system. No sound at all? That points to an electrical issue (fuse, relay, wiring) or a completely dead pump.
Check the Simple Stuff: Fuses and Relays
Don’t skip this! Many a rider has replaced a perfectly good pump only to find a blown fuse. Consult your owner’s manual to locate the fuel pump fuse and relay. Pull the fuse and inspect it. If it’s blown, replace it with one of the exact same amperage. If the new fuse blows immediately, you have a short circuit that needs to be traced.
The Definitive Check: A Fuel Pressure Test
This is the only way to know for sure if your pump is doing its job. You’ll need a fuel pressure test kit, which can be bought or often rented from an auto parts store.
Locate the Fuel Line: Find the fuel line connecting to the engine’s fuel rail. On the Outlander 570, access may require removing some plastic body panels.
Relieve Pressure: Before disconnecting any lines, relieve the fuel pressure. You can often do this by pulling the fuel pump fuse and running the engine until it stalls.
Connect the Gauge: Disconnect the fuel line and tee the pressure gauge in between the line from the tank and the fuel rail. Ensure all connections are secure to prevent leaks.
Test the Pressure: Re-install the fuse and turn the key to the “on” position. The pressure should jump up immediately. For a 2018 Outlander 570, you’re looking for a pressure reading of approximately 51 PSI (± 2 PSI). If it’s significantly lower, fails to hold pressure, or drops off while the engine is running, you’ve found your culprit.
How to Replace Your 2018 Can-Am Outlander 570 Fuel Pump: A Step-by-Step Guide
Ready to get your hands dirty? This job is very manageable for a careful DIYer. We’ll walk you through the entire process. Following these steps is one of the best 2018 can am outlander 570 fuel pump tips we can offer.
Gather Your Tools and Parts
Having everything ready makes the job go smoothly. You’ll need:
- A new fuel pump assembly (we recommend a complete assembly for reliability)
- A new fuel tank gasket/seal
- Basic socket and ratchet set
- Screwdrivers (Phillips and flathead)
- Pliers
- Clean rags
- Safety glasses and gloves
- A Class B fire extinguisher (non-negotiable)
- Optional: A fuel pump lock ring tool or a brass punch and mallet
Step 1: Preparation and Safety
First, run the fuel tank as low as possible. The less fuel you have to deal with, the better. Disconnect the negative terminal of your battery to prevent any accidental sparks. Move your ATV to a clean, open, and well-ventilated workspace.
Step 2: Access the Fuel Pump
You’ll need to remove the seat and any plastic body panels covering the fuel tank to gain clear access to the top of the tank where the pump is located. Take your time and keep track of all the bolts and clips.
Step 3: Disconnect and Remove the Old Pump
Thoroughly clean the area around the fuel pump assembly to prevent dirt from falling into the tank.
Disconnect the main electrical connector going to the pump.
Disconnect the fuel line. There will be some residual fuel, so have a rag ready to catch it. The connector usually has a small clip you need to press to release it.
Now, remove the large plastic or metal lock ring holding the pump in place. A special tool is best, but you can often tap it counter-clockwise carefully using a brass punch (to avoid sparks) and a mallet.
Once the ring is off, gently and carefully lift the entire fuel pump assembly straight up and out of the tank. Be mindful of the float arm so you don’t bend or break it.
Step 4: Install the New Fuel Pump
This is essentially the reverse of removal. Proper installation is a key part of our 2018 can am outlander 570 fuel pump best practices.
Inspect the inside of the tank for debris. If you see any, clean it out carefully.
Place the new rubber gasket/seal onto the tank opening.
Carefully lower the new pump assembly into the tank, making sure the float arm moves freely and the pump is oriented correctly (there’s usually an alignment tab).
Thread the lock ring back on by hand, then tighten it securely. It needs to be tight enough to create a good seal but be careful not to cross-thread or crack the plastic ring.
Reconnect the fuel line (you should hear a “click”) and the electrical connector.
Step 5: Final Checks and Priming
Reconnect your battery’s negative terminal. Before trying to start it, cycle the key to the “on” position for 3 seconds, then “off.” Repeat this 3-4 times. This allows the new pump to prime the system and fill the fuel lines. During this process, carefully inspect for any fuel leaks around the lock ring and fuel line connection. If you see or smell fuel, STOP and fix the leak.
Once you’re sure there are no leaks, fire it up! It should start right up and run smoothly.
A Sustainable Choice: The Eco-Friendly Benefits of a New Fuel Pump
Thinking about a sustainable 2018 can am outlander 570 fuel pump might seem odd, but it makes sense. A failing pump causes an engine to run inefficiently, burning more gas and creating higher emissions. By replacing it, you ensure a complete and efficient combustion process.
This not only restores your ATV’s performance but also reduces its environmental footprint. A well-maintained machine is an eco-friendly 2018 can am outlander 570 fuel pump choice because it burns cleaner and lasts longer, reducing waste.
Frequently Asked Questions About the 2018 Can-Am Outlander 570 Fuel Pump
Can I just replace the pump motor instead of the whole assembly?
While it is possible to buy just the internal motor, we highly recommend replacing the entire assembly. The assembly includes a new fuel filter, pressure regulator, and float sensor. For a DIY mechanic, swapping the whole unit is much faster, easier, and eliminates other potential failure points, giving you more peace of mind on the trail.
How much does a new fuel pump cost?
Prices can vary widely. An OEM (Original Equipment Manufacturer) pump from Can-Am will be the most expensive, often several hundred dollars. High-quality aftermarket assemblies are a great alternative, typically ranging from $100 to $250. They often provide excellent performance and reliability for a fraction of the OEM cost.
Is this a good project for a beginner?
We’d rate this as an intermediate-level job. While not overly complex, it requires care, attention to detail, and a healthy respect for working with gasoline. If you’re comfortable with basic tools and follow safety procedures carefully, you can absolutely do this. If you have any doubts, there is no shame in taking it to a trusted professional mechanic.
Tackling this job yourself not only saves you a significant amount of money but also gives you a deeper understanding of how your machine works. By following this guide, you’ve gained the knowledge to diagnose and fix one of the most common issues that can sideline a rider.
Now, put those plastics back on, double-check your work, and get ready to hit the trails with confidence. Ride smart, stay safe, and enjoy the ride!
