The volatile phase filter is located between the reducer and the injector rail in sequential gas injection systems. Its task is to protect the injector rail and the engine against solid contaminants contained in LPG gas, which could disturb the engine's operation or damage the installation. The filter should be replaced once a year or every 15,000 km.

The filter insert is made of high-quality paper that captures dirt particles as small as 5 μm!

The socket is adapted to the BOSCH or MST-400 ELTEK pressure sensor.
