Fig. 4 Fuel filter/water separator. 1984---87 C, K, R & V models
1984---87
The water separation system on these models is incorporated into the fuel filter assembly, Figs. 3 and 4. The fuel filter separates and traps water
contained in the fuel, and when the water level reaches a point where it could be drawn into the system, the ``WATER IN FUEL'' lamp on the instrument
panel is illuminated. In addition, the low pressure sensor on the filter outlet will also illuminate the lamp if the fuel filter becomes clogged.
