check fuel injector for leakage.
 Start engine for running check.

Fuel Injector Replaceability

Only allow to replace the fuel injector with one
with the same part number.

Blocking of Fuel Injector

The accumulation of fuel impurities may cause
flow offset and shorten fuel injector life. When the
engine is standing, the heat of engine may produce fuel
precipitation through the head of fuel injector, and the
precipitation gathered in the injection hole may cause
flow offset.
 Blockage may cause many problems, such as
small flow, large friction and accumulation of
impurities, and ultimately affect emissions and
durability.
 Fuel and environmental factors may cause fuel
crystallisation or fuel injector corrosion, which
may also cause flow offset.
 Poor oxidation stability of fuel may cause
precipitation, so please use high-quality
gasoline.
 Add an appropriate amount of fuel cleaner to
avoid precipitation.
 If fuel injector is blocked, please clean injector
according to the following cleaning method.
