2008 Can Am Spyder Fuel Pump: Complete Replacement Guide, Symptoms, and Best Options

If you own a 2008 Can-Am Spyder and suspect the fuel pump is failing, the bottom line is this: you can replace just the fuel pump itself for around $80 rather than spending $510 or more on a complete OEM assembly, and the job is doable at home if you are patient and mechanically inclined. The fuel pump in your 2008 Spyder GS 990 is an electric module located inside the fuel tank, and it is a known wear item on these machines . This guide walks you through the symptoms, the replacement process, what to look for in a replacement pump, and why upgrading to a quality aftermarket pump like KEMSO is often the smartest move for your wallet and your ride.

How the Fuel Pump Works on a 2008 Can-Am Spyder

The 2008 Can-Am Spyder GS 990 uses a multi-point electronic fuel injection system with dual 57mm throttle bodies, and fuel delivery is handled by an electric fuel pump module that sits inside the fuel tank . This is not a simple inline pump; it is a complete assembly that includes the pump itself, a fuel strainer, internal hoses, a fuel level sender with float arm, and a pressure regulator. The OEM part number for this assembly is 709000088, and it serves the entire 2008 Spyder GS line, including both the 5-speed manual and the semi-automatic SE5 versions .

The pump pushes fuel at a rate that matches OEM specifications, and it operates at 12 volts minimum with a flow rate of about 100 to 120 liters per hour at 3.0 bar . The assembly is a white plastic module that is mounted in the top of the tank and secured with a snap ring, and it includes the internal filter and corrugated fuel lines . When this pump starts to fail, the entire fuel delivery system suffers, and you will notice it in the way the engine runs.

Common Symptoms of a Failing Fuel Pump on a 2008 Spyder

A failing fuel pump does not always die suddenly. More often, it gives you warning signs first. Here are the most common symptoms owners report on the 2008 Spyder GS 990:

  1. Hard starting or long cranking before the engine fires. If the pump is not building up enough pressure quickly, the engine has to crank longer to get fuel to the injectors.
  2. Engine sputtering or hesitation during acceleration. A weak pump cannot maintain consistent pressure under load, which causes the engine to stumble.
  3. Loss of power at highway speeds. When the pump cannot keep up with demand, the engine starves for fuel and you feel a noticeable drop in power.
  4. A whining or humming noise coming from the fuel tank area. A pump that is working too hard will make noise, and this is often the first audible clue that the pump bearings or impeller are wearing out .
  5. The engine dies unexpectedly and will not restart. This is the final stage, and it usually means the pump has completely failed.

One owner on the SpyderLovers forum reported that the fuel strainer in his 2008 GS 990 had completely disintegrated, which allowed debris to reach the pump and cause it to fail . This is worth keeping in mind: if you are replacing the pump, you should also replace the strainer, and you should inspect the inside of the tank for any debris left behind.

What You Need to Know Before You Start

Replacing the fuel pump on a 2008 Can-Am Spyder is not a quick job. You need to remove the fuel tank completely, and that is the hard part. The tank sits in the frame in a way that prevents you from accessing the pump assembly with the tank still mounted, so there is no shortcut here . Plan for several hours of work, and be prepared for some frustration, especially when reinstalling the pump assembly and getting the O-ring to seat properly.

Here is what you will need:

  1. A new fuel pump that matches the OEM part number 709000088 or the later superseded part number 709000370 .
  2. A new fuel strainer if it does not come with the pump.
  3. New internal hoses if yours are cracked or broken. Owners have reported that these hoses crack and break with age, and they are not always included with aftermarket pumps .
  4. Basic hand tools, including a snap ring pliers to remove the retaining ring on the fuel pump assembly.
  5. Patience. Experienced owners report spending up to two hours just trying to get the O-ring and snap ring back in place .

The OEM fuel pump assembly sells for around $510, which is a lot of money for a part that is essentially a small electric motor and a plastic housing . Aftermarket pumps that replace just the pump itself are available for a fraction of that cost, and many owners have used them successfully.

How to Disassemble the Fuel Pump Assembly

If you have the assembly out of the tank, disassembling it is straightforward. The assembly is held together by two plastic tabs. You need to push these tabs in while pulling the assembly apart, and you can do this without breaking them if you are careful . Inside, you will find the pump, the strainer, and the internal hoses.

There are two hoses inside the assembly. One is marked "F" for fuel, and it connects to the fuel filter. The other is marked "R" for return, and it goes back to the intake manifold for venting. Both of these hoses can crack and break over time, so inspect them carefully. If either one is broken, you will need to source a replacement. Some aftermarket pumps come with one hose, but not always both, so check what is included in the kit before you order .

The fuel strainer on the bottom of the pump is also a wear item. If the strainer has disintegrated, you will need a new one, and it is important to get the correct size. One owner reported that the aftermarket strainer he received was much larger than the original and would not fit properly, so pay attention to the dimensions when ordering .

Step-by-Step Guide to Replacing the Fuel Pump

Here is the general process for replacing the fuel pump on a 2008 Can-Am Spyder GS 990:

Step 1: Remove the Fuel Tank

This is the most labor-intensive part of the job. You need to drain the fuel, disconnect the fuel lines, unplug the electrical connectors, and then unbolt the tank from the frame. The tank is heavy, so have a helper or a jack stand ready. Take your time and label everything so you know where it goes back.

Step 2: Remove the Fuel Pump Assembly

Once the tank is out, you will see the fuel pump assembly on top of the tank. It is held in place by a snap ring, which you need to remove with snap ring pliers. Lift the assembly out of the tank, being careful not to damage the fuel level float arm .

Step 3: Disassemble the Pump Module

Push in the two tabs on the sides of the assembly and pull it apart. You will now have access to the pump, the strainer, and the internal hoses. Inspect everything and replace any parts that are worn or broken .

Step 4: Install the New Pump

Remove the old pump from the housing and install the new one. If your new pump came with a strainer, install it now. Make sure the pump is seated correctly and that the electrical connections are secure. If you are using a KEMSO kit, the included wiring connector and crimp connectors make this step straightforward .

Step 5: Reassemble and Reinstall

Put the pump module back together, insert it into the tank, and secure it with the snap ring. This is the part that owners struggle with. The O-ring needs to be seated perfectly or the assembly will not go in straight. Take your time and work the O-ring around evenly. Once the snap ring is in place, reinstall the tank and reconnect everything.

Step 6: Test and Check for Leaks

Turn the ignition on (but do not start the engine) to prime the fuel system. Check for any leaks around the pump assembly and the fuel lines. If everything looks good, start the engine and let it idle for a few minutes, then check again for leaks.

Why KEMSO Is a Smart Choice for Your 2008 Spyder Fuel Pump

When you are shopping for a replacement fuel pump for your 2008 Can-Am Spyder, KEMSO stands out for a few important reasons. First, KEMSO pumps are built as high-performance, OEM-replacement units. The KEMSO 10614 pump delivers over 20% more flow than the stock pump at 43 psi, which means your engine gets the fuel it needs even under hard acceleration or when you are running at highway speeds . This extra flow can also help if you ever decide to make engine modifications that require more fuel.

Second, KEMSO pumps are designed for both gasoline and E85/ethanol, so they are compatible with the ethanol-blended fuels commonly sold in the United States . Ethanol can be hard on fuel system components, but KEMSO pumps are built with materials that resist the corrosive effects of ethanol, and they are tested to meet strict quality control standards .

Third, and most importantly, KEMSO backs their fuel pumps with a lifetime warranty . If the pump fails for any reason related to workmanship or materials, you can get a replacement at no cost. That is a level of protection that the OEM pump does not offer, and it gives you peace of mind knowing that your investment is protected.

The KEMSO 10614 pump kit includes everything you need for the installation: the pump itself, two gradient-density fuel strainers (so you can cover all Spyder models), a flex hose, a rubber base and cap, a Viton O-ring, a wiring connector, crimp connectors, and metal clamps . This is a complete kit that takes the guesswork out of the replacement process.

KEMSO fuel pumps cost around $80, which is a fraction of the $510 OEM assembly . When you factor in the lifetime warranty and the higher flow rate, KEMSO represents an excellent value for anyone who wants a reliable replacement pump without paying dealership prices.

Tips to Extend the Life of Your New Fuel Pump

Once you have a new pump installed, there are a few things you can do to make it last as long as possible:

  1. Keep your fuel tank at least a quarter full. The fuel pump relies on the fuel in the tank to keep it cool. Running the tank low causes the pump to run hotter, which shortens its life.
  2. Use quality fuel from a reputable station. Poor-quality fuel can contain contaminants that clog the strainer and damage the pump over time.
  3. Add a fuel system cleaner periodically. Some owners recommend adding a product like Marvel Mystery Oil to the fuel tank to keep the pump lubricated and quiet . This is not a substitute for regular maintenance, but it can help.
  4. Replace the fuel strainer at the same time as the pump. A clogged strainer forces the pump to work harder, which reduces its lifespan. It is cheap insurance to replace the strainer whenever you have the pump out.
  5. Inspect the internal hoses. The hoses inside the tank can crack and break with age, and if they fail, the pump will not deliver fuel properly. Replace them at the same time you replace the pump if they show any signs of wear .

Conclusion: Replace the Pump, Not the Whole Assembly

The 2008 Can-Am Spyder GS 990 fuel pump is a critical component, and when it fails, the symptoms are hard to miss. You do not need to spend $510 on a new OEM assembly when a quality aftermarket pump will do the job for around $80. The replacement process is time-consuming and requires patience, but it is doable at home with basic tools and a willingness to learn.

For most owners, the smartest choice is a high-performance aftermarket pump from a brand like KEMSO. You get better flow than stock, compatibility with ethanol-blended fuels, a complete installation kit, and a lifetime warranty. That combination of performance, durability, and value is hard to beat, and it will keep your 2008 Spyder running strong for many more miles.
