FUEL SYSTEM DESCRIPTION AND OPERATION
The fuel system includes a REMOTE-MOUNTED
electric fuel pump.
NOTE: The electric fuel pump MUST NOT be mounted
directly on the engine assembly, as engine vibration
will shorten the life of the pump.
The fuel pump regulates and maintains fuel flow to the
carburetor which is mounted on the intake manifold.
Depending on engine application, either a Holley
Model 1940, or Zenith Model 33 carburetor will be
used to provide necessary fuel for combustion.
Carburetor Identification
The carburetor identification tag is attached to the
upper body of the carburetor. The basic part number
for all carburetors is 9510. To procure replacement
parts, it is necessary to know the part number prefix
and suffix.
