Dodge B-I-B 1948 - Fuel Pump and Fuel Filter; Air Cleaner; Springs and Shock Absorbers

The idling mixture can be adjusted by turning the adjusting
screw. Not more than one quarter turn should be required at
any time.
The engine
idling speed can be regulated by turning the throttle
stop screw.
Adjustme ri ts should be made only when the engine is thoroughly
warmed up.
FUEL PUMP AND FUEL FILTER
Fuel is furnished to the carburetor by a mechanically driven fuel
pump. All fuel is filtered to remove any sediment or water that may
find its way into the fuel supply tank. The filter bowl screws into
the carburetor. Remove this bowl occasionally and clean the filter
element.
AIR CLEANER
It is important that the air cleaner be serviced as recommended on
the
lubrication chart, page 17.
FUEL GAUGE OPERA nON
The fuel gauge operates by means of small electr'o-magnets
controlled by a variable resistance unit linked to a float in the fuel
tank. Electric current is supplied to the gauge from the ignition
switch. Thus when the switch is turned off the indicator moves to the
Empty position. When the ignition switch is turned to the On position,
the fuel gauge instantly indicates the amount of fuel in the tank.
Construction of the gauge is simple. The register unit contains two
small magnetic coils, one of which exerts a constant force on the
needle while the other, which is wired to the resistance unit in the
tank, exerts an opposing force which varies in proportion to the
amount of fuel.
SPRINGS AND SHOCK ABSORBERS
In designing the springs of your truck, Dodge engineers have worked
out carrying capacities and rates of action that enable the springs
to carry the maximum recommended load with a reasonable mar-
