🔌 Function

The fuel injector seal kit seals the injector into the fuel rail and manifold, helping prevent fuel leakage and maintain correct pressure at the injector.

Common signs replacement is needed:

• Fuel smell around intake manifold

• Fuel leakage at injector seal

• Hard starting after injector or rail service

• Rough idle from poor injector sealing

• O-rings cracked, swollen or flattened

• Loss of fuel pressure at rail

• Replacement required when injector is removed

• Leak stops after new seal kit is fitted
