Who this list is for
This list is for replacing external fuel injector seals on a gasoline engine only where the factory procedure permits service. The seal kit and lubricant must be matched to the engine, and the fuel system must be depressurized first.
How to use this list
Read factory service information before gathering parts. Confirm the vehicle-specific fuel injector seal kit, then lay out the compatible O-ring lubricant, socket set, ratchet, torque wrench, fuel line disconnect tool if required, non-marring pick set, and plastic pry tool. Place absorbent shop towels and a fuel-safe drain pan below the work area before opening any fuel connection.
Common mistakes
Do not work on a pressurized fuel system. Do not reuse damaged seals or use a lubricant that is not compatible with gasoline. Avoid metal picks that can nick sealing surfaces. Keep ignition sources away, wear gloves and safety glasses, and have the listed flammable-liquid-rated fire extinguisher accessible.
What is on this list
This checklist includes the seal kit, approved O-ring lubricant, fuel-line tool if needed, non-marring picks, torque tools, towels, fuel-safe drain pan, safety gear, fire extinguisher, and factory information. Cross off tools you own, but do not substitute generic seals for engine-matched parts.
