FIGURE 6—Assembly Sequence Double Action Fuel Pump (Carter)
Vacuum Pump Test (Double Action Fuel Pump)
With engine idling, turn on the vacuum
windshield wiper to make certain the wiper
motor is in operating condition.
Disconnect the vacuum pump line at the
manifold and plug the manifold fitting. With
the engine running, windshield wipers should
operate; if they slow down a trifle, but do
not stop, the pump is satisfactory.
A.C. Type Fuel Pumps
The following tests apply to the A.C. double
action fuel pump.
On Engine
PRESSURE TEST—disconnect the fuel line to
the carburetor and install a tee fitting;
connect a fuel pump gauge to one port and
plug the remaining opening. Operate the
engine at 1800 R.P.M. on the existing fuel
in the carburetor. The pressure should be 4
to 5 P.S.I. Stop the engine and observe the
pressure. If it falls
leaking valves are indicated.
VOLUME TEST—disconnect the pressure gauge
and connect the fuel line to the tee fitting
and a rubber hose to the remaining opening
of the tee fitting.
Operate the engine at normal idle speed.
The fuel pump should fill a one pint measure
held at carburetor

off perceptibly,
float bowl height in one minute maximum.
Assembly on the Engine
Carter and A.C. Fuel Pump
The fuel pump cam lever is installed under the
cam of the engine camshaft.
CARBURETORS
Specifications for Carter Climatic Control
carburetors are listed on Page 13. Adjustment
procedures follow.
Float Adjustment
The bowl cover gasket must be removed. Invert
the bowl cover assembly so that the float is
resting on the seated needle by its own
weight. The height of the float is measured
between the bowl cover and the top of the
float when held horizontal at eye height
(Figs. 7 and 8).
Models WGD-2231-S and WGD-2252-S
Adjust the float level by bending the float
arm. Avoid straining the float. Do not grasp
the float shell while bending the arm.
Models WA1-2013-S, WA1-2009-SA, WA1-2113-S,
and YF-2014-S
The float level is adjusted by bending the lip
of the float, not the float arm.
