| Component | Service Life | Recommended Action | | :--- | :--- | :--- | | | 60,000 - 100,000 miles | Replace injectors as a set if leaking or if performance degrades. Some Vialle systems use a semi-sequential injection strategy (e.g., grouped as cylinders 1+2 and 3+4), and it is essential to confirm the correct strategy and replacement parts for your specific LPE unit. | | In-Tank Fuel Pump (PTC) | 100,000+ miles | Use a specialized diagnostic tool to monitor fuel pressure and pump current draw. A failing pump will draw excessive current. | | Discharge Pipes & O-Rings | As needed | Inspect for wear or damage during routine LPG servicing, especially if engine issues arise. | | Electrical Connections | Lifelong | Visually inspect soldered and crimped connections in the LPi wiring harness, as corrosion or cracking is a common source of electrical faults. | Once pure liquid presence is established in the
