Aurora V8-4.0L VIN C (1996)
Fuel Tank Unit: Description and Operation
Modular Fuel Sender Assembly
DESCRIPTION
The modular fuel sender assembly is attached to the top of the fuel tank, and extends from the top of the fuel tank to the bottom.
COMPONENTS
Modular Fuel Sender
The modular fuel sender assembly consists of the following major components: a Fuel Sender Cover Assembly (1), a Fuel Sender, Fuel Pipes
(Above Cover) (2), a Fuel Sender Support Assembly (3), a Fuel Pump, a Fuel Pump Strainer, a Fuel Pump Fuel Reservoir (4), a Fuel Sender
Strainer (5), a filter to reduce radio frequency interference on supercharged models, and a (6) Fuel Level Sensor Assembly.
Fuel Sender
The fuel level sender assembly consists of the float, the wire float arm, and the rheostat. The fuel level is sensed by the position of the float and
float arm, which operate the 90 ohm rheostat. As the float position changes, the amount of current passing through the rheostat varies, thus
changing the gauge reading on the instrument panel.
FUEL SENDER STRAINER
A woven plastic fuel sender strainer (5) is attached to the lower end of the fuel sender in the fuel tank. The functions of the fuel sender strainer are to
filter contaminants and to wick fuel.
The life of the fuel sender strainer is generally considered to be that of the fuel sender. The fuel sender strainer is self-cleaning and normally requires
no maintenance. Fuel stoppage at this point indicates that the fuel tank contains an abnormal amount of sediment or water, in which case the tank
should be thoroughly cleaned. If the fuel sender strainer is plugged, replace it with a new one.
