The electrical system relies on a dedicated wiring harness that splices into the vehicle’s factory engine management system.
The hydraulic loop of the Vialle LPi system is pressurized significantly above standard tank pressure to prevent the liquid fuel from boiling in the fuel lines due to engine bay heat.

Two synthetic lines replace the traditional single copper pipe to facilitate fuel circulation.
Liquid LPG expands and evaporates when injected into the intake port. This phase change creates a volumetric shrinkage in temperature, cooling the incoming combustion air. Denser air allows for a higher volumetric efficiency, preventing the 5-10% power loss typical of vapor systems. The electrical system relies on a dedicated wiring

The pump elevates the fuel pressure to ensure the propane remains completely liquid, even when exposed to high under-bonnet temperatures. Liquid LPG expands and evaporates when injected into
It continuously reads engine RPM, manifold absolute pressure (MAP), and system voltage to fine-tune the delivery. The Switch and Fuel Level Indicator
Original Siemens/Vialle LPI injectors typically register a low impedance profile between 1.2 Ωcap omega Ωcap omega .
Use a backing wrench on the filter body to prevent twisting the high-pressure copper or thermoplastic lines. Slowly loosen the filter housing cap.
