The Liquid Treatment Chamber (LTC) rail distributes liquid fuel uniformly across all injectors.

Measure current draw of the pump motor. High current indicates mechanical binding.

The ECU communicates with the vehicle via the CAN-bus or analog signals. It intercepts the petrol injector pulses and translates them into LPG injector pulses, applying correction factors (maps) stored in the "chip" or memory.

The LPI Vialle system is designed to operate in a variety of modes, including:

Replace the in-tank liquid pump assembly; replace fuel filter. Dropping rail pressure; Partially clogged fuel filter.
