If the fuel injector does not turn smoothly, the cause may
be that the O-ring is getting caught. Remove the fuel
injector, check the O-ring for damage and re-connect the
fuel injector to the delivery pipe assembly and then
re-check.

4.

Align the Fuel injector mating mark with the delivery pipe
mating mark.

5.

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

Caution
Do not let any engine oil get into the delivery pipe.

turns smoothly.

3.

If the hose does not turn smoothly, the O-ring is probably
being clamped. Disconnect the high-pressure fuel hose
and check the O-ring for damage. After this, re-insert the
delivery pipe and check that the hose turns smoothly.
