before you pour the fuel out of the tank fill spout into
the fuel container.
Note:
If you remove the fuel tank, you will need to
disconnect the fuel hose and electrical connectors from
the fuel pump and sending unit ; refer to
Fuel Pump and Sending Unit (page 46)
2.
Flush the tank with fresh, clean fuel, if necessary.
3.
Replace the fuel filters; refer to
