2007 Can Am Outlander 500 Fuel Pump: Complete Replacement Guide and Expert Buying Advice

If you own a 2007 Can Am Outlander 500 and your engine is hard to start, sputtering under load, or stalling at idle, the fuel pump is almost certainly the problem. The 2007 Can Am Outlander 500 fuel pump is an in-tank electric unit that delivers pressurized fuel to the EFI system, and it is a known wear item on these machines after 15+ years of service. Replacing it with a quality aftermarket unit is a straightforward job that most owners can handle in a weekend, and you have several excellent options depending on your budget and how much work you want to do. This guide walks you through everything you need to know to get your Outlander running right again.

Why the Fuel Pump Fails on the 2007 Outlander 500

The 2007 Outlander 500 uses an electric fuel pump mounted inside the fuel tank. This pump draws fuel from the tank and delivers it to the engine's fuel injection system at a consistent pressure, with excess fuel returning to the tank through a return line. Several factors cause these pumps to fail:

1. Age and mileage - After 15 to 20 years, the internal brushes, commutator, and electrical connections simply wear out. The pump motor draws more current and delivers less flow until it eventually stops working altogether.

2. Ethanol-blended fuel - Modern gasoline with ethanol absorbs moisture and can corrode internal pump components. The pump's internal seals and bearings degrade faster with ethanol exposure.

3. Contaminated fuel - Dirt, rust, and debris that accumulate in the tank over the years get pulled into the pump, eventually clogging the internal filter or scoring the pump mechanism.

4. Heat exposure - ATVs used in hot climates or for extended riding sessions subject the fuel pump to extreme thermal stress, accelerating wear on the electric motor.

Symptoms of a Failing Fuel Pump on the 2007 Outlander 500

Watch for these warning signs before your Outlander leaves you stranded:

1. Hard starting - The engine cranks but takes longer to fire, because the fuel system cannot build proper pressure quickly enough.

2. Loss of power under load - The machine feels sluggish, especially on hills or during hard acceleration, because the fuel pressure drops when demand increases.

3. Sputtering at speed - The engine cuts out briefly or surges at highway speeds, indicating intermittent fuel delivery problems.

4. Whining noise from the tank area - A loud, high-pitched whine from the fuel tank area indicates the pump is working harder than it should, often a sign of a clogged strainer or low fuel pressure.

5. Engine stalls when hot - The pump fails after the machine heats up, then restarts once it cools down, which points to an electrical or heat-related pump failure.

Replacement Options for the 2007 Can Am Outlander 500 Fuel Pump

When you shop for a replacement fuel pump for your 2007 Outlander 500, you will find three main categories of products. Each has distinct advantages and trade-offs.

1. Complete Fuel Pump Assembly (Recommended)

This is the easiest and most reliable option. A complete assembly, such as the Quantum HFP-A233 or the Fuel Pump Factory FPA-1080, drops directly into the fuel tank and plugs into the factory harness with no modifications required. It includes everything you need, including new gaskets and seals.

Benefits of choosing a complete assembly:

• Direct OEM replacement with guaranteed fitment
• No wiring modifications or guesswork
• Includes new tank seal, lock ring, and mounting hardware
• Corrosion-resistant housing that resists seizing
• Compatible with modern ethanol-blended gasoline
• Backed by a lifetime warranty from quality brands

2. Fuel Pump Rebuild Kit

These kits, like the All Balls 47-2015, provide all the individual components needed to rebuild the original pump module from your ATV. You reuse the existing housing and other metal parts, which saves money but requires more work.

What you typically get in a rebuild kit:

• Replacement electric pump motor
• New fuel strainer or filter
• Replacement hoses and clamps
• Wiring harness connectors

The main downside is that you are keeping the old plastic housing, which may be brittle after years of fuel exposure. If the housing cracks or the threads are stripped, the entire assembly needs replacement regardless.

3. Bare Pump Only

For those who really want to save money, you can purchase just the electric pump motor itself, such as the KEMSO 13802 which delivers 200 liters per hour at 43 psi. These pumps offer over 20% more flow than the stock unit, which can be a performance upgrade.

However, be aware of what you take on:

• You must disassemble the entire fuel pump module from your ATV
• You need to correctly route new hoses and attach new connectors
• You risk damaging delicate plastic components during disassembly
• The job requires a fuel-safe workspace, and you need to properly dispose of old fuel

How to Choose the Right Fuel Pump for Your 2007 Outlander 500

Before ordering any replacement part, verify your specific model year and configuration. The 2007 Outlander 500 uses a specific pump that is shared with several other Can-Am models from the same era.

1. Confirm your model year - The 2007 Outlander 500 uses the 703500771 fuel pump assembly. This part number also fits the 2007-2008 Outlander 400, 650, and 800 models, as well as the Renegade 500 and 800.

2. Check your VIN - Some very early 2006 models may have subtle differences in wiring connectors. Cross-reference your VIN with the parts chart to be certain.

3. Decide on assembly vs. kit - For most owners, a complete assembly is worth the extra money. It eliminates the risk of installation errors and gets you back on the trail faster.

4. Look for ethanol compatibility - All modern replacement pumps must handle E10 fuel. Premium brands specifically engineer their pumps with upgraded polymers and corrosion-resistant coatings for exactly this purpose.

Step-by-Step Installation Guide for the 2007 Outlander 500 Fuel Pump

The following steps apply to replacing the complete fuel pump assembly on your 2007 Outlander 500. Allow two to three hours for the job, and work in a well-ventilated area free of ignition sources.

Tools and materials needed:

• Socket set with extensions
• Torx drivers (T25 and T30 bits)
• Flat-blade screwdriver
• Clean shop rags
• Safety glasses and gloves
• New fuel pump assembly
• Anti-seize compound (optional)

Procedure:

1. Disconnect the battery - Remove the negative terminal first to eliminate any chance of electrical sparks near fuel vapors.

2. Access the fuel pump - The fuel pump sits under the seat or inside a service panel behind the rider. Remove the seat and plastic covers to reach the top of the fuel tank.

3. Relieve fuel pressure - Remove the fuel pump fuse, then crank the engine for a few seconds to bleed off residual pressure. Disconnect the fuel line connector carefully and have rags ready to catch any remaining fuel.

4. Remove the retaining ring - Use a large flat-blade screwdriver or a plastic pry tool to loosen the locking ring that secures the pump module to the tank. Turn it counterclockwise until it releases.

5. Lift out the old assembly - Gently twist and lift the entire pump module out of the tank. Take care not to bend the float arm on the fuel level sender.

6. Inspect the tank - Check the inside of the fuel tank for rust, debris, or varnish deposits. If the tank is dirty, clean it thoroughly before installing the new pump.

7. Install the new assembly - Lower the new pump assembly straight into the tank, making sure the gasket seats correctly. Align the tabs and tighten the locking ring clockwise until snug.

8. Reconnect fuel lines and wiring - Push the fuel line connector back on until it clicks firmly. Reconnect the electrical harness to the pump.

9. Test before reassembly - With the battery reconnected, turn the ignition key to the "ON" position (do not start the engine). You should hear the fuel pump prime for 1 to 2 seconds, then shut off. If it does not prime, check your electrical connections.

10. Reassemble the machine - Once you confirm the pump primes and there are no leaks, reinstall the seat and body panels. Start the engine and let it idle a few minutes to verify smooth operation.

Pro Tips for Long Fuel Pump Life on Your Outlander

1. Do not run the tank low - The fuel pump relies on fuel for cooling and lubrication. Running the tank to empty frequently shortens pump life significantly.

2. Change the fuel filter regularly - A clogged filter forces the pump to work harder, increasing electrical load and heat. Follow the recommended service interval for your machine.

3. Use fresh, high-quality fuel - Ethanol blends attract moisture over time. If you do not ride often, add a fuel stabilizer to keep the fuel fresh and prevent corrosion inside the tank.

4. Inspect the tank vent - A blocked vent creates vacuum in the tank, making the pump work harder. Make sure the vent hose is clear during your routine maintenance.
