Fuel Pump Tests
Carter Type Fuel Pumps
The following tests apply to both the single
and double action type Carter fuel pumps.
On Engine
VOLUME TEST—one quart of fuel in one minute
maximum at 500 Engine R.P.M.
VACUUM TEST—minimum of 10" mercury
(vacuum) at 500 Engine R.P.M. Fuel line from
the pump to carburetor must be disconnected
so pump will operate at full capacity.
PRESSURE TEST-3-1/2 to 5 P.S.I. at 500
Engine R.P.M. on the "Hornet" 6 and V-8
Series combination fuel and vacuum pumps;
3-1/2 to 4-1/2 P.S.I. at 500 Engine R.P.M.
on the single action fuel pumps, all Series.
Test is made with a pressure gauge connected
to a "T" fitting at the carburetor. The
pressure gauge connecting hose must not exceed
six inches in length.
IMPORTANT: Inaccurate pressure read-
ings will result if a "T" fitting is
not used or if a hose in excess of 6"
is used.
