Fuel Reservoir: Description and Operation
Fuel Pump/Gauge Sender Unit (Typical Reservoir)
PURPOSE
The fuel tanks of all Jeep models are equipped with a fuel reservoir. The reservoir provides fuel to the fuel pump inlet of fuel injected vehicles.
The reservoir is used during all driving conditions especially when the fuel tank has a low level of fuel. The reservoir is a small tray with raised
sides that the fuel pump inlet or fuel sender sets in. The fuel return tube empties into the reservoir. The fuel reservoir assures that the fuel pump
inlet is always submerged in fuel.
