Fuel Tank (see Fuel Tank Removal)
Fuel Hose (see Fuel Hose Replacement in the Periodic
Maintenance chapter)
Be sure to place a piece of cloth around the fuel outlet
pipe of the fuel pump and the delivery pipe of the throttle
body assy.
WARNING
Fuel is flammable and explosive under certain con-
ditions and can cause severe burns. Be prepared
for fuel spillage; any spilled fuel must be completely
wiped up immediately. When the fuel hose is dis-
connected, fuel spills out from the hose and the
pipe because of residual pressure. Cover the hose
connection with a piece of clean cloth to prevent
fuel spillage.
