Removing Fuel Pump Assembly
1. Remove the key from the ignition switch.
! WARNING
Always ensure that power cannot be inadvertently
applied to the ignition/ECM when working on the fuel
system. If the ignition switch is turned on, the electric
fuel pump will start and gas could be rapidly pumped
and spilled resulting in fire and severe injury.
2. Remove the passenger seat; then disconnect the neg-
ative battery cable.
3. Disconnect the electrical plug (A) from the main har-
ness; then disconnect the fuel hose (B) from the fuel
pump.
