1.Fuel delivery pipe side (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 degrees to push up the
retainer and unlock the fuel high-pressure hose connector. (3)
Remove the fuel high-pressure hose.
|
|
2.Vehicles side (1)
Remove the stopper of the fuel high-pressure hose. (2)
Raise the retainer of the fuel high-pressure hose and pull out the fuel high-pressure
hose in the direction shown in the figure.
|
note |
If the retainer is released, install it securely after removing 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. 3.If the rotation is not smooth, the O-ring may be caught. Remove the fuel injector
assembly and check the O-ring for damage. After this, re-insert it to the fuel delivery pipe
and check for its smooth rotation.

and fix the fuel injector assembly and fuel delivery pipe.
|
|
1.Apply a small amount of petrol to the O-ring at the end of fuel injector assembly.
|
|
2.
caution |

to the inlet manifold, pay attention to avoid damage to the O-ring at the end of the fuel injector assembly.
|
Install the fuel delivery pipe and fuel injector assembly to the inlet manifold.
|
|
3.Tighten the mounting bolts of the bracket and the injector protector rear loosely.
|
|
4.Loosen the inlet manifold mounting nuts and bolts, and the six injector protector front
mounting bolts. 5.Loosen the inlet manifold stay mounting bolts (Refer to GROUP 15 - Inlet
