Above is an example of 4 Cylinder Injector Rails.

The Landi Renzo gas injectors are the best in the world. They are a "side-fed" injector which reduces, substantially, the possibility of blockage and failure by contaminated gas.

A strong and robust electric motor, which gives the injector its distinctive clicking sound, is triggered by the Gas ECU allowing a controlled amount of Gas to enter the engine at the correct time. The injectors can deliver enough gas to "feed" 40KW's per cylinder. They are available in 3 sizes and configurations of 4, 6, and 8 cylinder engines.
