1.Follow the steps below to unlock the fuel high-pressure hose connector.
(1)
Insert a flat-tipped screwdriver (6 mm wide and 1 mm thick) into the retainer of the fuel
high-pressure hose connector.
(2)
|
|
| caution |
When pushing up the retainer of the fuel high-pressure hose
connector, pay attention to avoid damage to the retainer.
|
|
Turn the flat-tipped screwdriver inserted into the retainer by 90° to push up
the retainer and unlock the fuel high-pressure hose connector.
2.Remove the fuel high-pressure hose.
|
|
|
Remove the fuel delivery pipe with the fuel injectors attached to it.
|
|
1.Apply a small amount of petrol to the O-ring.
2.While turning the fuel injector to right and left, install the O-ring to the fuel
injector with care to avoid damage to the O-ring.
|
|
|
1.Apply a small amount of petrol oil to the O-ring.
|
|
2.Using special tool O-ring installer (MB992106), install the fuel injector paying attention
to avoid damage to the O-ring.
|
|
|
1.Apply a small amount of petrol to the O-ring.
|
|
2.Turning the fuel injector assembly to right and left, install it to the fuel delivery
pipe with care not to damage the O-ring. After the installation, check for its smooth rotation.
At this time, check that the projection part of the fuel injector assembly is in the centre.
