2009 Can-Am Renegade 800 Fuel Pump: Complete Replacement Guide for Owners

The bottom line up front: If you own a 2009 Can-Am Renegade 800 and you're dealing with hard starts, sputtering at full throttle, or a machine that stalls unexpectedly, the fuel pump is almost certainly the culprit. The 2009 Can-Am Renegade 800 uses an in-tank electric fuel pump assembly that is known to wear out over time, and replacing it with a quality aftermarket unit is the most practical and cost-effective fix. This guide covers everything you need to know—from identifying symptoms and choosing the right part to installation tips and cost expectations—so you can get your Renegade back on the trail without overpaying or guessing.

The 2009 Can-Am Renegade 800 was built as a high-performance sport ATV, and its EFI system depends on steady fuel pressure delivered by an electric pump mounted inside the fuel tank. This pump is not a serviceable wear item in the traditional sense, but it does have a finite lifespan. Many owners report pump failures between 3,000 and 6,000 miles, especially if the machine sits for long periods with ethanol-blended fuel in the tank. The good news is that replacement options are plentiful, ranging from bare pumps to complete modules, and most of them are direct bolt-in replacements that require no wiring modifications .

This guide will walk you through the symptoms of a failing fuel pump, the correct part numbers for your 2009 Renegade 800, the difference between bare pumps and complete modules, and a step-by-step replacement process. We will also highlight a few brands worth considering, including a dedicated section on KEMSO fuel pumps, which offer high-performance upgrades with a lifetime warranty. By the end, you will know exactly what to buy and how to install it, saving you both time and money compared to dealership service.

Symptoms of a Failing Fuel Pump on the 2009 Renegade 800

Before you order any parts, you need to confirm that the fuel pump is actually the problem. A weak or failing fuel pump on the 2009 Can-Am Renegade 800 produces a predictable set of symptoms. Here is what to look for:

  1. Hard starting or extended cranking – The engine turns over but takes longer than usual to fire. This happens because the pump cannot build adequate fuel pressure before the starter engages .
  2. Sputtering or hesitation under load – The Renegade feels flat when you open the throttle, especially in higher gears or when climbing. This indicates that the pump cannot keep up with the engine's fuel demand at higher flow rates .
  3. Sudden stalling or dying – The machine loses power without warning and may not restart for several minutes. This occurs when the pump overheats or seizes intermittently .
  4. Whining noise from the fuel tank – A loud, high-pitched whine coming from under the seat or tank area is a classic sign of a pump that is struggling. Healthy pumps run quietly .
  5. Check engine light with fuel pressure codes – If your Renegade displays a code related to fuel pressure or fuel trim, the pump is a prime suspect .

Keep in mind that these symptoms can also be caused by a clogged fuel filter, a faulty fuel pressure regulator, or a dirty fuel strainer. However, on a 2009 machine with significant mileage, the pump itself is statistically the most likely failure point. If you have verified that the fuel filter and fuel lines are clear, and you still experience the symptoms above, plan to replace the pump .

Which Fuel Pump Part Number Fits a 2009 Can-Am Renegade 800?

The 2009 Can-Am Renegade 800 uses the same fuel pump assembly as several other Can-Am models from the same era, including the Outlander 400, 500, 650, and 800, as well as the Renegade 500. The original OEM part number most commonly cited for this generation is 703500766, with updated supersessions listed as 703500771, 709000194, 709000245, and 709000378 . If you are looking up parts online, you will see these numbers referenced as the original equipment (OE) equivalent across many aftermarket listings.

Some sources also list the OEM fuel pump part number for the Can-Am 800 series as 420883153 for 2008–2012 models . This number appears in some dealer catalogs and service manuals, but the aftermarket community overwhelmingly references 703500766 as the practical replacement part. To avoid any confusion, always verify your specific vehicle's VIN against a dealer parts diagram before ordering, especially if you live in a market where model year designations differ slightly .

When shopping for aftermarket replacements, you will find that most brands list the compatible OEM part numbers right on the product page. A typical listing will state that the pump "Replaces 703500766, 709000287, 709000194, 709000245" . This cross-reference system makes it easy to match the right pump to your machine, even if the original part number has been superseded by Can-Am over the years.

Bare Fuel Pump vs. Complete Fuel Pump Module: What Do You Need?

One of the most important decisions you will make is whether to buy just the pump itself or an entire fuel pump module. Understanding the difference saves you money and prevents you from buying the wrong thing.

1. Bare fuel pump replacement

A bare fuel pump is just the electric pump unit itself, without the plastic housing, float arm, or fuel level sender. This option is cheaper and makes sense when your original module's housing, wiring, and regulator are still in good shape. Many 2009 Renegade 800 owners choose this route because the factory module is generally reusable. However, it takes more effort to disassemble the old module and swap just the pump .

2. Complete fuel pump module

A complete module includes the pump, the plastic flange, the fuel strainer, the pressure regulator, and sometimes the tank seal and retaining ring. This is the easiest option to install because you simply remove the old module and drop in the new one. It costs more, but it eliminates the guesswork and reduces the risk of a future failure caused by a worn regulator or aging plastic parts .

For a 2009 Renegade 800, a complete module from brands like All Balls or QuadBoss is a popular choice because it restores the entire fuel delivery system to like-new condition . If your machine has more than 5,000 miles, the added cost of a module is worth it. If your machine has low miles and you are confident the housing is clean, a bare pump is a more economical route .

Step-by-Step Guide: How to Replace the Fuel Pump on a 2009 Renegade 800

Replacing the fuel pump on your 2009 Can-Am Renegade 800 is a job you can do in a weekend garage session, provided you are comfortable with basic tools and follow safety precautions. Fuel system work always carries a risk of fire, so work in a well-ventilated area and disconnect the battery before you start.

Here is the general process:

  1. Relieve fuel pressure – Remove the fuel pump fuse, then crank the engine briefly to release pressure in the lines. Disconnect the battery negative terminal as a safety precaution.
  2. Remove the seat and fuel tank – On the Renegade 800, you will need to remove the seat and then disconnect the fuel lines, vent hose, and electrical connector from the pump module. The tank can be unbolted and lifted away, or in some cases accessed directly from above depending on the year and trim .
  3. Remove the pump module retaining ring – Use a spanner wrench or screwdriver and mallet to rotate the lock ring counterclockwise. Lift the module or pump assembly straight out of the tank.
  4. Replace the pump or module – If replacing just the pump, disconnect the old pump from the plastic housing, transfer the rubber mount and strainer to the new pump, and reassemble inside the original housing. If using a complete module, skip this step entirely and simply set the new module in place .
  5. Reinstall and test – Set the new assembly back into the tank, rotate the lock ring clockwise to secure it, reconnect fuel lines and wiring, and reinstall the tank and seat. Reconnect the battery, turn the ignition to "ON" without starting the engine to prime the system, check for leaks, and then start the machine.

The entire job typically takes 1.5 to 3 hours for a first-time owner. Make sure you have new gaskets or O-rings if your kit includes them; some complete modules come with a fresh tank seal, which is a nice bonus because old seals often harden and leak after removal .

Cost Expectations for a 2009 Renegade 800 Fuel Pump

Pricing for a 2009 Can-Am Renegade 800 fuel pump varies widely depending on the type of part and brand you choose.

A bare aftermarket pump can cost as little as $26 to $40, which is a remarkably affordable option if you reuse the existing module . Rebuild kits that include the pump plus necessary hoses, clamps, and filters typically run in the $60 to $90 range . Complete fuel pump modules, which include everything you need for a direct swap, typically cost between $150 and $330 depending on the brand and whether it is a premium upgrade .

For reference, a dealership will often charge $500 to $700 in parts and labor for a fuel pump replacement on a 2009 Renegade 800. Doing the work yourself with a quality aftermarket part can cut that cost by half or more, making this one of the most cost-effective maintenance jobs you can perform on this machine.

Selecting a Reliable Fuel Pump Brand for Your 2009 Renegade 800

1. All Balls

All Balls is one of the most recognized names in aftermarket ATV parts. Their fuel pump kits are designed for plug-and-play installation, and their rebuild kits include all necessary components like the pump, filter, hoses, clamps, and wiring harness . The All Balls complete module (part number 47-1049 or 47-1049_21) covers the 2009–2012 Renegade 800 and is specifically engineered to draw less current than the OEM pump while maintaining the same flow rate at working pressure, which reduces heat buildup and extends pump life .

2. QuadBoss

QuadBoss offers a complete fuel pump module for Can-Am Outlander and Renegade models from 2009 to 2012. Their module includes all necessary components and is also tuned to draw less current than OEM units. The QuadBoss part number 401048 is application-specific and designed to restore your fuel system to factory standards . It is a bit more expensive, but the build quality is solid and it comes with a good reputation in the powersports community.

3. KEMSO (Highly Recommended)

KEMSO is a manufacturer that specializes in high-performance fuel pumps for ATVs, UTVs, motorcycles, and watercraft. Their pumps are designed as direct OEM replacements, meaning they match the dimensions and connector of the stock pump, so you can install them without modifying the wiring or the fuel tank . But the key difference with KEMSO is performance: KEMSO's pump for the Renegade 800 (part number 13803) delivers 200 liters per hour at 43 psi, which is over 20% more flow than the stock OEM fuel pump . This additional flow provides a safety margin for engines that are modified or ridden hard, and it also compensates for aging fuel lines and filters that add resistance over time .

KEMSO pumps are built with upgraded materials and a machined exterior finish, and every pump is individually flow tested before it leaves the factory . The pump is compatible with both gasoline and E85/ethanol fuel blends, which is important for owners who ride in regions where ethanol content is high . KEMSO offers a lifetime warranty on their pumps, which tells you they trust the durability of their product . You can find the KEMSO fuel pump specifically for the Can-Am Renegade 800/800R 2007–2015 on their official website at https://www.kemsoracing.com/. They provide detailed fitment charts and technical specifications for each application, and their customer support team is responsive if you have questions about which pump fits your exact model .

Performance Specifications to Look For

Regardless of which brand you choose, here are the specifications you should verify before buying a fuel pump for your 2009 Renegade 800:

  1. Amperage draw – A good aftermarket pump should draw 5.3 amps at 40 psi and 6.0 amps at 60 psi, which is typical for this application . A lower amperage draw at the same flow rate reduces heat and extends pump life .
  2. Flow rate – Look for a pump that delivers at least 145 liters per hour at 40 psi and 119 liters per hour at 60 psi to match or exceed OEM performance . The KEMSO 13803 pump significantly exceeds this with 200 LPH at 43 psi .
  3. Body diameter and length – The pump body should be 1.5 inches in diameter and roughly 2.5 inches in metal case length, with an inlet diameter of 3/8 inch and outlet diameter of 3/8 inch .
  4. Fuel compatibility – Make sure the pump you choose is compatible with modern ethanol-blended pump gasoline. Ethanol can degrade cheap pump seals and impellers, so this is not a specification to overlook .

Important Installation Notes and Safety Tips

Working on a fuel system is inherently risky. Here are a few things every 2009 Renegade 800 owner should keep in mind:

  • Always relieve pressure first – Failure to do so can result in a spray of fuel when you disconnect the lines. This is both a fire hazard and an environmental concern.
  • Replace the strainer – If you are reusing your old module, make sure the gradient density fuel strainer is in good condition. A clogged strainer can restrict flow just like a bad pump .
  • Check the wiring connector – The electrical connector on the 2009 Renegade 800 can corrode over time. Inspect it for green or black residue before reinstalling, and clean it thoroughly if needed .
  • Use a new tank seal – The rubber o-ring or gasket that seals the module to the tank can compress and harden over years of service. Reusing it may result in a fuel leak. Many complete modules and KEMSO kits include a fresh tank seal .
  • Do not mix brands of pump and module – If you are buying a bare pump, make sure it is designed to fit inside the OEM module you are reusing. Aftermarket modules have different internal dimensions, and a pump from one manufacturer may not seat properly in another brand's module .

How to Extend the Life of Your New Fuel Pump

A fuel pump on the 2009 Renegade 800 will last significantly longer if you follow a few simple habits:

  • Keep the tank mostly full when storing – A full tank reduces the amount of air inside, which means less condensation and less moisture in the fuel. Moisture promotes corrosion and can damage the pump internals.
  • Use fuel stabilizer if the machine sits for more than a few weeks – Ethanol-blended fuel can break down and form varnish that clogs the pump inlet or the strainer. A stabilizer prevents this .
  • Replace the inline fuel filter per the maintenance schedule – A clogged filter forces the pump to work harder, which raises its operating temperature and shortens its life .
  • Avoid running the tank dry – The fuel pump uses the surrounding fuel for cooling and lubrication. Running the tank to empty exposes the pump to higher temperatures and can accelerate wear .
