>>B<< INJECTOR INSTALLATION

caution

Use care not to let gasoline enter the delivery pipe.

1.Apply gasoline to the O-ring.
2.Insert the injector into the delivery pipe.
3.Make sure the injector rotates smoothly. If not, remove the injector to check the O-ring for damage, and replace the O-ring if necessary. Then reinsert the injector and check that it rotates smoothly.

>>C<< O-RING INSTALLATION

When inserting an O-ring into the injector on the injection nozzle side, use special tool O-ring installer (MB992106) to gradually expand the O-ring, and fit it in place.

>>D<< INJECTOR SUPPORT INSTALLATION

1.Make sure that the protrusion of the injector is at the centre as shown in the illustration.

2.Securely assemble the injector to the injector groove and delivery pipe collar.

>>E<< FUEL HIGH PRESSURE TUBE INSTALLATION

caution

Pay attention that the o-ring of the quick connector has neither scratches nor a fall.

1.Insert the quick connector of the fuel high pressure tube into the delivery pipe.
2.Fit the retainer of the fuel high-pressure tube in the direction shown in the illustration.

note

Make sure the fuel high pressure tube is not pulled out when pulled lightly.

note

Must confirm there is play of about 1 mm between quick connector and delivery pipe.

>>F<< SPARK PLUG INSTALLATION

Using special tool Spark plug wrench (MB991398), tighten the spark plug to the specified torque.
Tightening torque: 18 ± 2 N·m
