Note: The following is based on the procedure for my R1100R which should be
similar to other oilheads.
1. Ride the bike until you are almost out of gas or siphon the gas from the tank.
2. Remove the seats.
3. Remove the right side black plastic panel below fuel tank.
4. Remove the fuel tank bolt, 6mm hex bit socket, right side of fuel tank.
5. Set the tank to the side of the bike – lawn chair with an old blanket to prevent
scratching the tank.
6. With the tank on its side, remove the fuel pump plate, 8mm socket.
7. Disconnect the fuel overflow and vent hoses – the 2 small hoses inside the
tank, noting which hose goes where.
Warning! Do not get any of the hoses mixed up! Label them.
8. Remove the pump unit from the tank.
9. Replace the fuel filter noting the direction of flow.
10. Reconnect the new fuel filter using the 2 small hose clamps.
11. Insert a new o-ring into the tank groove.
Note: The original o-ring swells and will not fit unless you let it "dry" for a few
days.
12. Insert the pump unit into the tank.
13. Reconnect the 2 small hoses being sure to connect the striped hose to the
striped hose using the 2 tiny hose clamps.
14. Evenly tighten the fuel pump plate, 8mm socket.
