2018 Can-Am Outlander 570 Fuel Pump: The Complete Guide to Diagnosis, Replacement, and Top Performance Upgrades
The bottom line: If your 2018 Can-Am Outlander 570 is hard to start, sputters under load, or stalls unexpectedly, the fuel pump is the most likely culprit. Replacing it with a high-quality aftermarket unit—especially one that delivers more flow than the stock pump—will restore your ATV's performance and reliability. You can do this job yourself in a few hours with basic tools, and the payoff is a machine that runs like new.
Recognizing the Warning Signs: When Your Fuel Pump Is Failing
Fuel pump failure on the 2018 Outlander 570 doesn't happen overnight, but it gives you plenty of warning. The most common symptoms include difficulty starting the engine, especially after the ATV has been sitting for a while. You might also notice sputtering or surging during acceleration, which indicates inconsistent fuel delivery. Another telltale sign is a loss of power under load—when you're climbing a hill or towing something, the engine just doesn't have the punch it used to. In more advanced cases, the engine may stall unexpectedly while riding, and in the worst scenario, it simply won't start at all .
A failing fuel pump also causes the engine to run inefficiently, burning more gas and producing higher emissions. By replacing it, you ensure a complete and efficient combustion process, which not only restores performance but also reduces your ATV's environmental footprint. A well-maintained machine burns cleaner and lasts longer .
Step 1: Quick Diagnosis Before You Buy Anything
Before you order a new pump, you need to confirm the problem is the pump itself and not something simpler. Start with the basics:
Check the fuse and relay. Using your owner's manual, find the fuse and relay for the fuel pump. Visually inspect the fuse for a broken element. Then swap the fuel pump relay with an identical one from another circuit—like the horn relay—to see if the problem goes away. A faulty relay is a common and inexpensive failure point .
Listen for the priming sound. Turn the ignition key to "ON" (but don't start the engine). Listen carefully near the fuel tank. You should hear a distinct humming sound for 2-3 seconds as the pump primes the system. No sound suggests an electrical issue—blown fuse, bad relay, wiring fault—or a completely dead pump .
Check for voltage at the pump. Disconnect the electrical connector to the pump assembly. With the ignition on, check for 12 volts at the harness connector terminals that power the pump. If voltage is present but the pump doesn't run, the pump motor is confirmed dead. If no voltage is present, the issue is in the wiring, switch, or ECU .
Step 2: Choosing the Right Replacement Fuel Pump
Once diagnosis is confirmed, selecting the correct replacement part is crucial. You have several options, each with its own considerations.
Genuine OEM (Original Equipment Manufacturer) Pump: This is a direct replacement part sourced from Can-Am/BRP. It is guaranteed to fit perfectly and match the original performance specifications. The main advantage is guaranteed compatibility and reliability. The primary disadvantage is cost, as OEM parts are usually the most expensive option .
High-Quality Aftermarket Replacement Pump: Numerous reputable aftermarket brands manufacture fuel pump modules specifically for the 2018 Outlander 570. Brands like Quantum Fuel Systems, Delphi, All Balls Racing, and KEMSO offer units that meet or exceed OEM specifications. These provide an excellent balance of quality and value. It is critical to purchase from a trusted supplier and ensure the part is listed explicitly for your exact model and year .
Complete Pump Module vs. Pump-Only Kit: The fuel pump is usually sold as a complete "module" or "assembly." This includes the pump, reservoir, filter sock, pressure regulator, and fuel level sender. Replacing the entire module is often recommended as it renews all internal components that wear simultaneously. Some suppliers offer "pump-only" kits, which involve transferring your existing housing and sender. This is more labor-intensive and only advisable if the rest of your assembly is in perfect condition .
For the 2018 Can-Am Outlander 570, the OEM part number is typically 709000461. Many aftermarket assemblies, including those from Quantum and All Balls, use this same interchange number, making it easy to find a compatible replacement .
Step 3: Tools and Parts You'll Need for the Job
Replacing the fuel pump on a 2018 Outlander T3 570 is a manageable task for a DIY enthusiast with proper mechanical caution. Always work in a well-ventilated area, away from sparks or open flames.
Tools needed:
- Socket set and ratchet with extensions
- Screwdrivers (flathead and Phillips)
- Fuel line disconnect tools (to avoid damaging quick-connect fittings)
- Pliers and hose clamp pliers
- A large spanner wrench or a brass drift and hammer (for the locking ring)
- Shop towels and a container for any fuel spillage
- Safety glasses and gloves
Parts needed:
- New fuel pump module assembly (OEM or high-quality aftermarket)
- New fuel filter (if separate from the module)
- A small amount of fresh gasoline for testing
Step 4: Step-by-Step Replacement Guide
Safety First: Depressurize and Disconnect Power
Ensure the vehicle is on a level surface. Turn the ignition OFF. Relieve fuel system pressure before starting by removing the fuel pump fuse and cranking the engine for a few seconds. This will release any residual pressure in the lines. Then disconnect the negative battery terminal to prevent any electrical shorts or sparks during the process .
Access the Fuel Pump Module
The fuel tank is located under the seat and rear bodywork. You will need to remove the seat and the plastic shroud or cover that sits over the tank. On the T3 model, this typically involves removing several bolts and clips. Once the pump module's locking ring is visible, carefully clean any debris from around it to prevent contamination from falling into the tank .
Disconnect Electrical and Fuel Lines
Disconnect the electrical connector from the pump assembly. Then, using the appropriate fuel line disconnect tools, disconnect the fuel supply and return lines. Have a rag handy to catch minor fuel spillage. Be thorough—any leftover pressure can spray fuel when you disconnect the lines .
Remove the Old Pump Module
Using a special spanner wrench or a large blunt tool (a brass drift and hammer works well), unscrew the large plastic locking ring that holds the pump module in the tank. Turn it counterclockwise. Do not use a steel screwdriver as it can crack the plastic ring or the tank. Once loose, carefully lift the entire assembly out of the tank. Be mindful of the attached fuel level float arm so as not to damage it .
Transfer the Fuel Level Sender (If Required)
If you purchased a pump-only kit, you must now carefully transfer the fuel level sender unit from your old assembly to the new pump housing. Follow the instructions provided with your kit precisely. If you have a complete module, you can skip this step—it's one of the main reasons to buy a full assembly instead of a pump-only kit .
Install the New Pump Module
Compare the new module with the old one to ensure they are identical. Lower the new assembly into the tank, aligning it correctly with the tabs or notches in the tank. Hand-tighten the locking ring securely. Do not overtighten, as it is plastic and can crack. Reconnect the fuel lines, ensuring they click firmly into place. Reconnect the electrical connector until it clicks .
Reassemble and Test
Reinstall the tank cover, shrouds, and seat. Reconnect the battery. Turn the ignition to "ON" and listen for the new pump to prime for 2-3 seconds. Check all connections for any fuel leaks. If you see or smell fuel, stop and fix the leak immediately. Finally, start the engine. It may take a few extra cranks to build pressure initially. Let it idle and check for smooth operation. Take a short test ride to verify normal performance under load .
Proactive Maintenance to Extend Your Fuel Pump's Life
Preventive care is far cheaper than a trailside recovery. Here's what you can do to make your new pump last:
Never run the tank dry. Make it a habit to refuel before the gauge drops below the quarter-tank mark. This is the single most effective practice for pump longevity. The fuel pump uses the gasoline in the tank for cooling and lubrication. Running low on fuel causes the pump to run hotter and wear faster .
Use high-quality fuel and additives. Purchase gasoline from reputable stations. For periods of storage exceeding 30 days, use a fuel stabilizer to prevent ethanol-related phase separation and varnish buildup that can clog the system. With pump gasoline now infused with as much as 15% ethanol in many parts of the country, compatibility with multiple fuel blends is an essential requirement for all fuel pump components .
Keep the battery in top condition. A weak battery or poor connections cause low voltage, which makes the pump motor labor harder, generating excess heat and leading to early failure. Ensure your battery is fully charged and the terminals are clean and tight .
