Diagram Ref No 4
Manufactured from premium fuel-resistant elastomer, the O-ring is engineered to withstand continuous exposure to petrol, engine heat, fuel pressure and repeated thermal cycling without hardening, cracking or losing elasticity. Precision-manufactured to the original dimensions of 7.52 x 3.53mm, it provides direct OE-style fitment and dependable sealing performance during injector installation, fuel system servicing or engine repairs.
What This Product Does:
- Creates a leak-free seal around the fuel injector.
- Maintains correct fuel system pressure.
- Prevents fuel leaks between the injector and its mounting point.
- Stops unmetered air from entering the fuel system.
- Protects surrounding engine components from fuel contamination.
- Supports efficient fuel delivery and combustion.
- Restores factory fuel system sealing performance.
- Forms an essential part of the engine fuel injection system.
Symptoms Of Wear Or Failure:
- Fuel smell from the engine bay.
- Visible fuel leaks around the injector.
- Difficult engine starting.
- Rough idle or engine misfires.
- Reduced engine performance.
- Increased fuel consumption.
- Loss of fuel pressure.
- Cracked, flattened or hardened O-ring.
- Fuel system fault codes.
- Increased fire risk due to fuel leakage.
Why Replacement Matters:
- The fuel injector seal O-ring is continuously exposed to fuel, high operating temperatures and pressure fluctuations. Over time, the sealing material naturally hardens, shrinks or becomes compressed, reducing its ability to provide an effective seal around the injector.
- A deteriorated O-ring can allow fuel to escape or unmetered air to enter the fuel system, affecting fuel pressure, combustion efficiency and overall engine performance. Fuel leaks within the engine bay also present a significant safety hazard and may damage surrounding components if left unresolved.
- Replacing the injector seal O-ring whenever a fuel injector is removed or serviced helps ensure a secure, leak-free fuel system and reliable engine operation. The OE Match Fuel Injector Seal O-Ring is manufactured to OE standards using premium fuel-resistant materials, providing factory-style fitment, dependable sealing performance and long-lasting durability, helping maintain the safety, efficiency and reliability expected from your Porsche.
