FUEL DRAINING PROCEDURE [SKYACTIV-D 1.8]

Home  id0114q9853500

Warning

•  Fuel is very flammable liquid. If fuel spills or leaks from the pressurized fuel system, it will cause serious injury or death and facility breakage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line Safety Procedure”, while referring to the “BEFORE SERVICE PRECAUTION”.

•  A person charged with static electricity could cause a fire or explosion, resulting in death or serious injury. Before draining fuel, make sure to discharge static electricity by touching the vehicle body.

1.  Complete the “BEFORE SERVICE PRECAUTION”. (See BEFORE SERVICE PRECAUTION [SKYACTIV-D 1.8].)

2.  Verify the fuel level in the fuel gauge and siphon the fuel.

STEP	FUEL TANK LEVEL	INSTRUMENT CLUSTER	RESULTS	FUEL SIPHONING PROCEDURE
1	Fuel tank level is 14/16 or more.		Yes	Perform the fuel siphoning procedure in the fuel-filler pipe. (See Fuel Siphoning Procedure in Fuel-filler Pipe.)
			No	Go to the next step.
2	Fuel tank level is 8/16 or more, or less than 14/16.		Yes	Perform the fuel siphoning procedure in the joint hose. (See Fuel Siphoning Procedure in Joint Hose.)
			No	Perform the fuel siphoning procedure in the fuel tank. (See Fuel Siphoning Procedure in Fuel Tank.)

Fuel Siphoning Procedure in Fuel-filler Pipe

Note

•  When removing the hose from the fuel-filler opening, use a rag to prevent fuel spatter.

•  Cut the tip of the hose diagonally so that it can be inserted into the fuel-filler pipe smoothly.

•  When inserting the hose into the fuel-filler pipe, the hose may get stuck. In such cases, rotate the hose so that the hose can be inserted easily.

1.  Siphon the fuel in the fuel-filler pipe.

(1)  Cut the tip of the hose diagonally and place a mark at the position of the specified hose insertion length.

Hose insertion length (specified value)

985 mm {38.8 in}

Hose type (reference)

Oil-resistant plastic hose of 10 mm {0.39 in} outer diam. ×6 mm {0.2 in} inner diam. or equivalent

(2)  Insert the hose from the fuel-filler opening by rotating it to the marked position.

(3)  Siphon the fuel until the fuel in the fuel-filler pipe is completely siphoned out.

2.  Perform the fuel siphoning procedure in the joint hose. (See Fuel Siphoning Procedure in Joint Hose.)

Fuel Siphoning Procedure in Joint Hose

Caution

•  If an excessive length of hose is inserted into the joint hose, the hose will push the non-return valve and the hose may enter the fuel tank. If the hose enters the fuel tank, the hose may get stuck on the non-return valve when the hose is pulled out and the non-return valve could be damaged. Do not insert the hose more than the specified length.

Note

•  When removing the hose from the joint hose (fuel-filler pipe side), use a cloth to prevent fuel spatter.

•  Cut the tip of the hose diagonally so that it can be inserted into the joint hose smoothly.

•  When inserting the hose into the joint, the hose may get stuck. In such cases, rotate the hose so that the hose can be inserted easily.

•  The pump siphons all the fuel that leaked out of the non-return valve and was trapped in the joint hose, then it suctions the air. After siphoning the fuel, wait several seconds until the air is suctioned out, then resume siphoning.

1.  Disconnect the joint hose from the fuel-filler pipe.

2.  Siphon the fuel in the joint hose.

(1)  Cut the tip of the hose diagonally and place a mark at the position of the specified hose insertion length.

Hose insertion length (specified value)

220 mm {8.66 in}

Hose type (reference)

Oil-resistant plastic hose of 10 mm {0.39 in} outer diam. ×6 mm {0.2 in} inner diam. or equivalent

(2)  Insert the hose from the joint hose (fuel-filler pipe side) by rotating it to the marked position.

(3)  Siphon the fuel until the fuel in the joint hose is completely siphoned out.

3.  Perform the fuel siphoning procedure in the fuel tank. (See Fuel Siphoning Procedure in Fuel Tank.)

Fuel Siphoning Procedure in Fuel Tank

2WD

1.  Remove the fuel gauge sender unit. (See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION [(E)].)

2.  Drain the fuel.

AWD

1.  Remove the fuel gauge sender unit (main). (See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION [(E)].)

2.  Siphon the fuel in the fuel tank (main).

3.  Perform the following procedure if the fuel gauge value before siphoning the fuel is 8/16 or more. If the fuel gauge value is less than 8/16, go to the next step.

(1)  Insert the hose into the fuel tank (main).

(2)  Direct the inserted hose into the fuel tank (sub).

(3)  Siphon the fuel in the fuel tank (sub).

Fuel siphoning amount (reference)

approx. 5.0 L or more

4.  Remove the fuel gauge sender unit (sub). (See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION [(E)].)

5.  Siphon the fuel in the fuel tank (sub).
