Fuel Filter: Description and Operation
COALESCING CNG FUEL FILTER
The coalescing CNG fuel filter is located between the high pressure lock-off solenoid and the high pressure regulator. The coalescing filter housing contains a 6-micron filter element as well as a drain fitting. The coalescing filter is designed to trap contaminates and liquids that may damage the gaseous fuel injectors. This filter must be periodically inspected, drained and replaced.
