Fuel Pump Replacement Guide
Before beginning the fuel pump replacement on your Can-Am 800, ensure you have the correct part number for the fuel pump. The part number for the Can-Am 800 fuel pump varies depending on the model year and specific version of the vehicle. Common part numbers include 420884080 or 420884084, but always verify compatibility with your vehicle’s VIN or consult a Can-Am dealership or parts manual. Once you have the correct part, gather the necessary tools: a socket set, wrenches, a flathead screwdriver, and a fuel line disconnect tool. Safety is paramount, so work in a well-ventilated area, wear safety goggles, and ensure the vehicle is on a stable surface with the engine turned off.
Step 1: Access the Fuel Pump
Locate the fuel pump, which is typically housed inside the fuel tank. Begin by relieving the fuel system pressure to avoid spills or accidents. Disconnect the negative battery terminal to prevent electrical hazards. Remove the seat and any plastic panels covering the fuel tank. Carefully place a drain pan under the fuel tank to catch any residual fuel. Using the appropriate tools, loosen the fuel tank mounting bolts and gently lower the tank to access the fuel pump assembly. Be cautious not to damage fuel lines or wiring during this process.
Step 2: Remove the Old Fuel Pump
With the fuel tank accessible, disconnect the electrical connector and fuel lines from the pump. Use a fuel line disconnect tool if necessary to avoid damaging the lines. Remove the retaining ring or bolts securing the fuel pump to the tank. Carefully lift the old pump out of the tank, taking note of its orientation for proper installation of the new one. Clean the fuel pump mounting area to ensure a secure fit for the replacement pump.
Step 3: Install the New Fuel Pump
Insert the new fuel pump (part number verified for your Can-Am 800) into the tank, ensuring it is aligned correctly. Reattach the retaining ring or bolts to secure the pump in place. Reconnect the fuel lines and electrical connector, ensuring all connections are tight and secure. Double-check that there are no leaks or loose components before proceeding.
Step 4: Reassemble and Test
Carefully lift the fuel tank back into position and secure it with the mounting bolts. Reinstall any panels or the seat that were removed earlier. Reconnect the negative battery terminal. Before starting the vehicle, turn the ignition to the "on" position for a few seconds to allow the fuel pump to prime. Check for any fuel leaks around the tank and connections. Once confirmed, start the engine and test the vehicle to ensure the new fuel pump is functioning correctly.
By following this detailed guide and using the correct part number for your Can-Am 800 fuel pump, you can successfully replace the component and restore your vehicle’s performance. Always refer to the manufacturer’s instructions or consult a professional if you encounter any difficulties during the process.

Common Fuel Pump Issues & Fixes
The Can-Am 800, a popular ATV model, relies heavily on its fuel pump to deliver consistent fuel flow to the engine. However, like any mechanical component, the fuel pump can encounter issues over time. One common problem is fuel pump failure, often indicated by difficulty starting the engine, sputtering, or a complete loss of power. If you suspect a faulty fuel pump, the first step is to verify the part number, which is typically 420884089 for the Can-Am 800. This ensures you purchase the correct replacement part. Before replacing the pump, check the fuel filter and lines for clogs or leaks, as these can mimic fuel pump issues.
Another frequent issue is electrical failure within the fuel pump assembly. The pump relies on a functional relay and fuse to operate, so a blown fuse or faulty relay can cause the pump to stop working. To diagnose this, use a multimeter to test the voltage at the pump’s electrical connector. If no voltage is detected, inspect the fuse box and relay under the seat or in the ATV’s electrical compartment. Replacing a blown fuse or faulty relay is a straightforward fix that can save you from unnecessarily replacing the entire pump.
Contaminated fuel is another culprit that can damage the fuel pump. Ethanol-blended fuels or water in the tank can corrode internal components, leading to reduced pump efficiency or failure. To prevent this, use high-quality fuel and consider adding a fuel stabilizer, especially if the ATV is stored for extended periods. If contamination is suspected, drain the fuel tank, clean it thoroughly, and replace the fuel filter before testing the pump again.
A weak or inconsistent fuel pressure can also indicate a failing fuel pump. This issue often manifests as poor acceleration or stalling under load. Use a fuel pressure gauge to test the pump’s output against the manufacturer’s specifications. If the pressure is below the recommended range, the pump may need to be replaced. Ensure the new pump is compatible with the Can-Am 800 by verifying the part number (420884089) and following proper installation procedures.
Lastly, excessive noise from the fuel pump area can signal an internal issue, such as a worn impeller or damaged check valve. While some noise is normal during operation, loud whining or grinding sounds warrant immediate attention. If the pump is noisy and showing other symptoms, such as reduced performance, replacement is often the best course of action. Always consult the ATV’s service manual for specific instructions on removing and installing the fuel pump to avoid damaging other components.
