By the installation seat during the
installation of the fuel injector.
DO: install it into the hole after being
applied with correct lubricant.
Protect the o-ring and reduce pollution.
DO: test the fuel injector adhered to
the needle valve or whose needle valve
fails in seating. (pulse to the fuel injector
with the voltage between 9-15V for less
than 5 seconds)
Confirm the invalidation of the fuel injector.
DO: before the fuel injector is
assembled, carry out fuel leakage test to
confirm seating of the needle valve.
The needle valve of the fuel injector may
fail in seating during transportation or
transfer, which causes fuel leakage.
DO: avoid liquid pollution to the fuel
injector.
Cause short-circuit of the electromagnetic
coil.
DO: carefully install/remove the cables.
Cause damage to terminals.
Should: use suggested lubricant during
the installation of the connector.
Cause corrosion to terminals.
DO: do not use dropped, damaged or
unqualified components, and label them
to indicate problems.
Find causes to problems as soon as
possible.

Installation Requirements
Please strictly comply with following instructions for installation and disassembly to avoid damage
to fuel injectors and electronic components.
● Lubrication: apply a little lubricant to the lower part of the o-ring. Do not use ISO 10 light
mineral oil or equivalent product.
● If it is possible, it is better to apply lubricant to the fuel injector seat other than the o-ring.
Thus, it can minimize pollution to the fuel injector.
● Do not make the orifice plate contact with lubricant, which affects the volume of fuel injection.
Do not pick up lubricant with the top of the fuel injector.
● All fuel injector o-rings are assembled before delivery. In principle, o-rings are not allowed to
be used repeatedly. Please check whether there is any damage to the o-rings. Any minor
damage will cause leakage. Install the o-ring into the holder carefully.
● Do not damage the connector when it is installed. The fuel injector connector is properly
installed when there is a click sound.
● Do not install or disassemble unnecessary connectors.
● Do not tighten cables too much, otherwise it may lead to short circuit.
● Do not rotate the fuel injector during the installation of the connector, which leads to deviation
from the fuel injection targets.

Replacement
The disassembly and replacement of the fuel injector are as follows.
