Denso-Common Rail System – Fuel filter

1 Fuel return (to the fuel filter)
2 Fuel return (to the fuel tank)
3 Fuel feed (to the high-pressure pump)
4 Air cleaner element minder gauge
5 Water-in-fuel sensor (certain markets only)
6 Water drain screw
7 Water-in-fuel sensor wiring harness
8 Fuel feed (from the fuel tank)

The fuel heater functions in a similar way to that in the Delphi common rail system via a bi-metal controlled control valve.
