and repeat the procedure from step 1.

3. Using special tool MB991654, tighten the bolts by the

following procedure.

>>C<< HIGH-PRESSURE FUEL HOSE INSTALLATION

CAUTION

Do not allow engine oil to enter the fuel rail.

1. Apply a small amount of new engine oil to the O-ring.

2. While turning the high-pressure fuel hose to the right and

left, install the fuel rail, while being careful not to damage the
O-ring. After installing, check that the hose turns smoothly.

3. If the hose does not turn smoothly, the O-ring is probably

being clamped. Disconnect the high-pressure fuel hose and
