FUEL FILTER ASSEMBLY
FUEL SYSTEM COMPONENTS
Incoming fuel (from the owner installed Gasoline Water
Separator/Filter) is pumped thru the Inlet Fuel Filter into the
Fuel Module by the Electric Fuel Pump. The fuel is cooled
as it circulates thru the Fuel Module and then is pumped by
the Elf!ctric Fuel Pump to the High Pressure Pump Modide
and to the Secondary Fuel Filter. The fuel passes to the Fuel
Rail and is delivered (utider pressure) to the Fuel Injectors.
