The submerged pump is the most common wear item in high-mileage systems. Over time, the internal bearings wear out due to paraffin deposits and contaminants found in commercial LPG.
Designed to meet modern environmental standards for CO2 and NOx reduction.
Proper installation is paramount for the Vialle system. Due to the high pressures and flammable nature of LPG, installation must only be performed by licensed professionals. The manual emphasizes:
Because fuel is in a liquid state, it can be metered with much higher accuracy, allowing the LPG system to closely mirror the performance of the original petrol injection system. lpi vialle technical manual top
: The system is operating on petrol but waiting through a warm-up phase (which can take up to 2 minutes) to complete the gas changeover.
: The "Combi-Switch" (gauge) uses 5 LEDs to show fuel levels (4 green for full, 1 red for empty). It allows manual switching between petrol (red LED) and LPG (green LED).

Run the vehicle on LPG, shut it off, and immediately relieve rail pressure or clamp the return line. If the car starts normally after sitting, the injectors are leaking and require servicing or replacement. System Switches Back to Petrol Automatically
For authorized technicians and owners, obtaining the official Vialle LPI documentation is critical. As noted in the documentation, it is essential to utilize reputable sources to ensure the accuracy of the technical data and to avoid security risks, such as malware or corrupted files. Always refer to the original manufacturer documentation for detailed schematics and diagnostic codes. Conclusion
