WARNING:
Read “General Precautions” when working on the fuel system. Refer to
.
REMOVAL
1.
Release the fuel pressure from the fuel lines. Refer to
2.
Check fuel level on a level ground. If the fuel level is at 1/2 or higher, drain enough fuel so that the level on
the fuel gauge is at half or below.
• This is to prevent overflow of fuel from the tank when the fuel level sensor unit, fuel filter and fuel pump
assembly is removed
• In the event of malfunction in fuel pump, insert a hose measuring less than 20mm (0.79 in) in diameter
into fuel filler tube through fuel filler opening to draw fuel from filler tube.
- Disconnect fuel filler hose from fuel filler tube. Refer to
- Insert hose into fuel tank through fuel filler hose to draw fuel from fuel tank.
3.
Disconnect batterie cable from negative terminal.
4.

- If quick connector sticks to tube of main fuel level sensor unit,
push and pull quick connectors several times until they start to
move. Then disconnect them by pulling.
CAUTION:
• Quick connector can be disconnected when the tabs are
depressed completely. Never twist it more than neces-
sary.
• Never use any tools to disconnected quick connector.
• Keep resin tube away from heat. Be especially careful
when welding near the resin tube.
• Prevent acid liquid such as battery electrolyte, etc. from
getting on resin tube.
• Never bend or twist resin tube during installation and dis-
connection.
