Yamaha Raider Fuel Pump Replacement
We went through all of the troubleshooting procedures for the fuel pump on our 2008 Yamaha Raider, and determined it was time to replace it with a new pump.
The fuel pump on the Raider is found underneath the seat, and requires the removal of brackets, hoses, panels and bolts to get to it. For the Yamaha Raider, it’s best to replace the fuel pump with a new OEM pump, plus the gaskets that go on the top and under it for a good seal.
Watch the video above or follow the steps below to learn how to change the fuel pump on a 2008 Yamaha Raider motorcycle.

How to Replace Yamaha Raider Fuel Pump
Step 1. Remove the seat from the motorcycle, followed by the cover below it.
Step 2. Disconnect the negative side of the motorcycle battery.
Step 3. Remove the retaining clip and the rubber caps from the valves that go to the fuel tank, then turn off the valves. Screw the valves all the way in and lightly seat them.
Step 4. Remove the center brackets (upper and lower), which you’ll have to go deep down to be able to remove. That includes removing the bolts that hold them in place, pushing out the lower retention pin for the fuel line, and taking the side panel off the bike.
The side panel is held in place by a security Torx T30 and a 4mm hex.
NOTE: There was some additional wiring on the bike from an unknown installation that needed to be removed as well to get to the fuel pump.
Step 5. Disconnect the power connection to the fuel pump by pushing it in and up.
Step 6. Remove the catch for the send, then start disconnecting all of the fuel hoses (or pipes) and their clamps connected to the pump.
Use side jaw pincers to remove the clamp from the fuel hose by squeezing it together and pulling it up to release it.
Step 7. Wipe down the top of the fuel pump with a clean cloth to make sure none of the dirt on it falls into the tank when it gets wiggled out.
Step 8. Remove the 4mm Allens that hold the fuel pump in place, followed by its retention plate (fuel pump bracket), then carefully lift out the fuel pump.
NOTE: Before pulling out the fuel pump, notice the orientation it goes in, and use the little notch for the retention plate as a reference point.
Step 9. Clean off the edge of the fuel tank carefully, without pushing any dirt down into it.
Step 10. Use a flashlight to look inside the fuel tank to make sure there's no dirt or debris in the fuel. If you find any, vacuum out the fuel.
Step 11. Install a new O-ring on the new fuel pump, then install the pump into the fuel tank.
Step 12. Replace the upper seal (damper plate) on the retention plate (gap facing up), then reinstall it and its Allens, tightening them in a crisscross pattern until they're all seated.
Step 13. Reconnect the hoses and their clamps to the fuel pump.
Step 14. Test the fuel pump by reconnecting the battery and using a test light to touch the wire that controls when the fuel pump is supposed to prime. The test light should light up for a few seconds, then shut off.
NOTE: Watch the video below if you need a more in-depth look at testing a motorcycle’s fuel pump.
NOTE: Make sure you tighten down the negative terminal of the battery if you didn’t already when you reconnected it.
Step 15. Release the valves for the fuel tank by unscrewing them until they top out.
Step 16. Reinstall the remaining brackets, caps, latches, plates and connections you removed to get to the fuel pump, and reconnect the vent on the side.
Step 17. Reinstall the side panel, the cover and the seat and you’re done.
