Fuel Line/Quick-Connect Fitting Precautions
Flammable - Keep Fire Away

NOTE:
Refer to the Fuel and Emissions Systems Service Precautions before disconnecting/connecting the fuel line.
Replace the fuel feed hose, fuel line, or the quick-connect fitting to new one if it is damaged.

When removing or installing the fuel feed hose/line, or when disconnecting or connecting the quick-connect fittings, pay attention to the following:
Not heat-resistance; Be careful not to damage them during welding or other heat-generating procedures.
Not acid-proof; Do not touch them with a shop towel that was used for wiping 12 volt battery electrolyte or something similar.
Not stress-resistance; Be careful not to bend or twist the fuel feed hose/line excessively.
Retainer Replacement
A disconnected quick-connect fitting can be reconnected, but the retainer on the mating line cannot be reused once it has been removed from the line.

NOTE: Use the same manufacturer retainer and the same size retainer when the replacing the retainer.

Fuel Line/Quick-Connect Fitting Removal
1.
Remove the fuel line/quick-connect fitting cover (If equipped).
2.
Check the fuel quick-connect fittings for dirt, and clean it if needed.

3.
Place a rag or shop towel over the quick-connect fitting.

4.
Hold the connector (A) with one hand, and squeeze the retainer tabs (B) with the other hand to release them from the locking tabs (C).

5.
Pull the connector off.

NOTE:
Be careful not to damage the line (D) or other parts. Do not use tools.
If the connector does not move, keep the retainer tabs pressed down, and alternately pull and push the connector until it comes off easily.
Do not remove the retainer from the line; once removed, the retainer must be replaced with a new one.
6.
Check the contact area (A) of the line (B) for dirt or damage.
If it is dirty, clean it.
If it is rusty or damaged, replace the damaged fuel line or the damaged part.
7.
To prevent damage and keep foreign matter out, cover the disconnected connector and line ends with plastic bags (A).

NOTE:
The retainer cannot be reused once it has been removed from the line.
Replace the retainer when:
?
replacing a new part that does not include the retainer. (a fuel line, a fuel tank unit etc.)
?
it has been removed from the line.
?
it is damaged.
Fuel Line/Quick-Connect Fitting Installation
1.
Check the contact area (A) of the line (B) for dirt or damage, and clean it if needed.
2.
Insert a new retainer (A) into the connector (B) if the retainer is damaged, or after:
replacing new part which does not pack with the suitable retainer. (a fuel line, a fuel tank unit etc.)
removing the retainer from the line.

NOTE: Use the same manufacturer retainer and the same size retainer when replacing the retainer.

3.
Before connecting a new fuel line/quick-connect fittings, remove the old retainer from the mating line.
4.
Align the quick-connect fittings (A) with the line (B), and align the retainer (C) locking tabs with the connector grooves.

5.
Press the quick-connect fittings onto the line until both retainer tabs lock with a clicking sound.

NOTE: If it is hard to connect, put a small amount of new engine oil on the line end.
6.
When replacing the fuel line with a new retainer as a set, make sure you remove the ring pull upwards after you confirm the connection is secure.

NOTE: Before you remove the ring pull, make sure the fuel line connection is secure. If the connection is not secure, the ring pull could break when you try to remove it.
7.
Make sure the connection is secure and the tabs are firmly locked into place; check visually and also by pulling the connector.
8.
Turn the vehicle to the ON mode, but do not start the engine. After the fuel pump runs for about 2 seconds, the fuel line will be pressurized. Repeat this two or three times, then check for fuel leakage.

9.
Set the groove of the quick-connect fitting cover on the fuel line as shown, then install it. Make sure the cover is firmly locked in place.
