08 GSXR 600 Fuel Pump: The Complete Guide to Replacement and Upgrades
Understanding Your GSXR600 Fuel Pump System
The 2008 GSXR600 uses an electric fuel pump mounted inside the fuel tank. This pump is part of a complete module that includes the fuel filter, pressure regulator, and fuel level sensor. When the pump fails, the most common symptoms include hard starting, sputtering at high RPM, loss of power during acceleration, or the engine cranking but not starting at all.
The stock pump delivers approximately 60-80 liters per hour at 43 psi, which is sufficient for the factory engine configuration. However, many riders find that after years of use, the pump loses efficiency due to wear, debris in the tank, or ethanol-related corrosion.
OEM vs Aftermarket Options
Your first decision is whether to buy an OEM Suzuki pump or an aftermarket replacement. Here is what you need to know about each option:
1. OEM Suzuki Fuel Pump
The factory pump carries part numbers 15100-37H00 and 15100-37H01-000 for the 2008-2010 GSXR600 models . These pumps are built to exact factory specifications and will plug directly into your existing module. The downside is cost – a new OEM pump can run several hundred dollars, and Suzuki only sells the complete assembly in some cases, which drives the price even higher.
2. Aftermarket Direct Replacement Pumps
Several reputable brands offer drop-in replacement pumps that match or exceed OEM performance. These pumps typically cost less than half the price of an OEM unit and often include additional components like new strainers, O-rings, and wiring connectors.

How to Install a Fuel Pump on Your 2008 GSXR600
Installing a new fuel pump on the GSXR600 is a straightforward job that most riders can complete in about an hour. Here is the general process:
Step 1: Remove the fuel tank
Drain the fuel tank completely. Remove the seat, then disconnect the fuel lines and electrical connector. Remove the mounting bolts and lift the tank off the bike.
Step 2: Access the fuel pump module
The pump module is located on the bottom of the tank. Remove the retaining ring using a spanner wrench or a punch and hammer. Carefully lift the module out of the tank.
Step 3: Disassemble the module
Remove the fuel level sensor and any brackets. Note how the pump is oriented inside the module. Disconnect the wiring and fuel hose from the old pump.
Step 4: Install the new pump
Place the new pump in the same orientation as the old one. Connect the fuel hose and wiring. Install the new strainer and O-rings that came with your kit. Reassemble the module.
Step 5: Reinstall the module
Place the module back into the tank, ensuring the gasket seals properly. Install the retaining ring and tighten it securely. Reinstall the fuel tank and connect all lines and wiring.
Step 6: Test the system
Turn the ignition on without starting the engine to allow the pump to prime. Check for fuel leaks. Start the engine and verify proper operation.
Performance Upgrade Considerations
If you are replacing a failed pump, you might as well consider an upgrade. The KEMSO 13501 pump delivers 200 liters per hour compared to the stock 60-80 liters per hour, which means it will easily support any engine modifications you might plan in the future . This extra flow capacity is beneficial if you plan to add a power commander, aftermarket exhaust, or performance air filter.
For riders who have installed turbochargers or larger displacement engines, the higher flow rate ensures that the engine never runs lean during hard acceleration. The pump is designed to operate at 43-68 psi, which covers the pressure range of most fuel injection systems.

Maintenance Tips for Fuel Pump Longevity
To get the most life out of your new fuel pump, follow these simple practices:
Keep your tank at least a quarter full. Running the tank low allows debris and sediment to be drawn into the pump, which can clog the strainer and damage the pump internals.
Use high-quality fuel. Cheap gasoline often contains more contaminants and water, which can cause corrosion inside the pump and fuel system.
Add fuel stabilizer during storage. If you store your bike for more than a month, add a fuel stabilizer to prevent ethanol-related corrosion and gumming.
Replace the fuel filter regularly. The strainer on the pump is the primary filter, but it can become clogged over time. Replace it whenever you replace the pump.
Check for rust in the tank. The GSXR600 is known for developing rust inside the fuel tank, especially in humid climates. If you see rust, clean the tank or replace it before installing a new pump.
