Service of fuel injectors begins with removing the
Fuel Rail which releases the Fuel Injector retainer clip and finally extracting the Fuel Injector. Toss away both the Fuel Injector retainer clip together with the Fuel Injector O-Ring seals (2, 4). Always obtain fuel injectors that match the specific application requirements before new installation. The fuel injectors display two markings: a part number id together with a four-digit code which declares manufacturing month, day, year and shift. The new Fuel Injector O-Ring seals (2, 4) need engine oil lubrication before being installed onto the Fuel Injector. A new retainer clip should be placed onto the Fuel Injector before inserting the Fuel Injector into the Fuel Rail injector socket with its electrical connector facing outward. The retainer clip should attach to a flange which exists on the Fuel Rail injector socket. Finally, reinstall the Fuel Rail.
