2009 Suzuki Boulevard C50 Fuel Pump: Complete Replacement Guide and Best Options

The bottom line up front: If you own a 2009 Suzuki Boulevard C50 and need a fuel pump, your primary factory part numbers are 15100-41F20 (for K6 models) and 15100-41F30 (for K7/K8/K9 models). The original equipment manufacturer (OEM) list price ranges from $483 for the K6 model to $227 for later models. However, you can find quality aftermarket replacements for as little as $46 to $80, offering substantial savings while maintaining reliable performance. This guide walks you through identification, symptoms of failure, replacement costs, and the best options available for your bike.

Understanding Your 2009 Boulevard C50 Fuel Pump

The Suzuki Boulevard C50 (also branded as the Intruder C800 in some markets) uses an electric fuel pump mounted inside the fuel tank. This pump delivers fuel from the tank to the fuel injection system at a consistent pressure, which is critical for proper engine operation. The 2009 model year falls into a compatibility window that covers 2006 through 2010 for most aftermarket replacement parts.

Critical detail on part numbers: The 2009 VL800C uses either of two fuel pump assemblies depending on when it was manufactured:

1. 15100-41F20 – Listed as "MODEL K6" in factory parts diagrams
2. 15100-41F30 – Listed as "MODEL K7/K8/K9" in factory parts diagrams

Both parts share most internal components, but the plate assembly also differs between these two versions. The K6 plate assembly (15410-41F20) costs around $331 retail, while the K7/K8/K9 version (15410-41F30) is about $156. When ordering a complete pump assembly, make sure you match the correct number to your specific bike.

Identifying a Failing Fuel Pump

Fuel pumps rarely fail without warning. Watch for these common symptoms that indicate your 2009 Boulevard C50 fuel pump needs attention:

• Hard starting or no-start condition – The engine cranks but struggles to fire or does not start at all because fuel is not reaching the injectors
• Engine sputtering at speed – You feel intermittent power loss, especially under acceleration or on the highway
• Loss of power under load – The bike lacks pull when climbing hills or carrying a passenger
• Whining noise from the tank – Unusual high-pitched sounds from the fuel tank area often indicate a pump straining to move fuel
• Poor fuel economy – A failing pump that cannot maintain proper pressure causes the engine to run rich or lean, hurting gas mileage

If you notice any of these, test the fuel pressure first. A healthy VL800 system should deliver around 43 PSI. Failing to replace a worn pump promptly can also damage other fuel system components, so early attention is worthwhile.

Complete Fuel Pump Assembly Components

The factory parts diagram for the 2009 VL800C shows the fuel pump as an assembly that includes more than just the electric pump motor. The full parts list includes:

• 15111-41F10 – Cushion (retail about $4.13)
• 15112-41F10 – Holder (retail about $5.99)
• 15115-10F00 – Band, fuel pump (retail about $4.20)
• 15116-10F10 – Screws (retail about $1.45 each)
• 15172-35F00 – Spring washer (retail about $2.69)
• 15173-35F00 – Nut (retail about $2.90)
• 15410-41F20 or 15410-41F30 – Plate assembly (the main mounting plate)
• 15420-41F10 – Strainer (retail about $20.33)
• 15425-41F10 – Vessel (retail about $5.72)
• 15201-35F00 – O-ring, fuel pump (retail about $11.37)
• 15810-41F00 or 15810-39G00 – Fuel hose (varies by model designation)
• 07120-0612A – Bolts for the fuel pump (retail about $0.41 each)

If your issue is limited to one component, like a cracked plate or a clogged strainer, you might not need a complete assembly. However, given that the average age of these bikes is now over 15 years, many owners choose complete pump replacement to avoid repeat failures.

Replacement Cost Breakdown

OEM pricing: Factory Suzuki parts are the most expensive route. Based on current parts catalogs, expect to pay around $227 to $483 for the pump assembly itself, depending on which version your bike uses. With the additional components, an OEM-level replacement can easily total $300 to $600.

Aftermarket assemblies: Complete aftermarket fuel pump assemblies for the 2009 VL800 are available from $46 to $164. For example:

• Rideicontrol lists a compatible assembly at $46
• Mad Hornets sells a brand new assembly with two temperature sensors for about $159
• ATVEngix offers the same-style pump at $81.78
• Fuel Pump Factory sells a replacement EFI pump with regulator at $79.99

Used OEM options: eBay occasionally has used OEM pumps in good condition. One example lists a used 2005–2009 C50 pump for $299.95. While used parts carry more risk, they offer original fitment at a reduced price compared to new OEM.

Rebuild kits: If your pump motor still works but the internal filter or valves are clogged, All Balls Racing offers rebuild kits. The kit number 47-2024 fits the 2009 C50 Boulevard and costs about $97.75. This is the most economical route for a mechanically inclined owner.

Installation Considerations

Replacing the fuel pump on a 2009 Boulevard C50 is a manageable DIY job for most home mechanics, but expect it to take 1 to 2 hours. Here is a quick overview:

1. Drain the fuel tank – Use a siphon pump to remove as much fuel as possible
2. Remove the fuel tank – Disconnect the fuel lines, electrical connectors, and the tank mounting bolts
3. Access the pump – The pump assembly sits in the tank and is held by a retaining ring or band
4. Transfer components – If your replacement is just the pump (not the full assembly), move the plate, strainer, and gasket from the old unit to the new one
5. Reinstall and test – Reconnect everything, refill the tank, and check for leaks

Some aftermarket suppliers note that professional installation is recommended and that instructions are not included. If you are not comfortable working on fuel systems, take the bike to a qualified motorcycle mechanic. Fuel system work carries fire and injury risks, so safety comes first.
