Test the power at the tank connection; check fuse holder integrity. Loose high-pressure crimp couplings or return valve leak. lpi+vialle+technical+manual
The fundamental goal of the Vialle LPi system is to mimic the vehicle's original petrol delivery as closely as possible. 1. Liquid Circulation lpi+vialle+technical+manual
The vehicle's original engine control unit operates as if the car is still running on petrol. The intercepts the fuel injector signals, calculates the density differences between petrol and liquid LPG, and adjusts the opening time of the gas injectors accordingly. 3. Cooling Effect lpi+vialle+technical+manual
By keeping the fuel in a liquid phase, the Vialle LPI system optimizes thermal efficiency, eliminates power loss common in older gas conversions, and uses the vehicle's factory engine electronics for highly accurate fuel metering. 🛠️ System Architecture and Core Components

The "Pump Tank Combination" (PTC) is fully submerged inside the tank's Multivalve. It circulates the liquid fuel at a constant pressure through the fuel lines and back to the tank.
