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.
