🔌 Function

The fuel injector seal kit seals the injector to the fuel rail and intake assembly, helping prevent fuel leaks and maintain correct fuel pressure and spray pattern.

Common signs replacement is needed:

• Fuel smell at intake manifold

• Fuel leakage from injector area

• Rough idle after injector removal

• Hard starting after fuel rail service

• Cracked or swollen injector O-rings

• Fuel rail pressure loss from poor sealing

• Injector removed and seals need replacement

• Leak stops after new injector seals are fitted

• Brand new

• Supplied in original or equivalent packaging
