(1).
CAUTION:
• Never bend float arm during removal.
• Never pollute the inside by residue fuel. Draw out avoid-
ing inclination by supporting with a cloth.
• Never cause impacts such by dropping when handling
components.
10. Separate fuel tube as per the following steps to remove fuel level sensor unit, fuel filter and fuel pump
assembly.
• Pinch quick connector (A) square-part with your fingers, and
