FUEL PUMP REPLACEMENT

WARNING
Always wear safety goggles when working with high
pressure or flammable fluids. Failure to do so could
result in serious injury or complications.
1. Remove the seat to access the fuel pump.
2. Disconnect the battery (-) negative cable.
3. Ensure that static has been discharged from you by
touching a ground source such as the engine or
frame.
4. Remove the fuel pump cover by pulling up on the
front edge.
5. While holding a shop towel over the fuel line
connector, disconnect the quick connect fuel line
from the fuel pump.
CAUTION
It is possible for pressurized fuel to be present when
disconnecting the fuel line.It is recommended to allow
the vehicle to sit for a period of one hour after shutting
off the engine before servicing the fuel pump. This
allows the exhaust to cool and fuel pressure to drop.
NOTICE
A small amount of fuel may come out of the fuel line or
tank. Properly drain fuel into a suitable container.
