What is a Gas Relay and how does it work? Sequential systems require time control. The gas ECU first opens float and gas valves, and then opens gas injections ……

Without a time control, the engine will stop as the gasoline supply is cut off before the gas injectors are opened.

While the vehicle is using LPG, the petrol pumps in the petrol tank continue to operate and pump petrol to the front.

Because gasoline is constantly circulated between the engine, tank and engine, it causes heating and expansion. The gasoline then evaporates from ventilation. This results in a decrease in gasoline content in the tank. The gasoline pump relay is required.

Due to constant emptying the gasoline tank, gasoline’s octane level and burning rate decrease. It is possible to put a petrol relay in the vehicle to stop the petrol pump from leaking.
