'91 Dodge Caravan, Gas Gauge Blues
Q:
When I get to just above half a tank on the gas gauge the low fuel light
comes on and then the gauge drops to empty on my 91 Dodge Grand
Caravan. Would this be the gauge or the unit inside the tank itself?
A:
I would bet coffee that the sending unit in the gas tank that
reports the fuel level is failing. Because of the vehicles age I
would suggest replacing the fuel pump when you have the sensor/sending
unit removed from the gas tank for replacement. Why? The fuel pump is
part of the gas gauge sending unit assembly so the labor cost should be
no different.
