FUEL SYSTEM
COMPONENTS
8
COMPONENTS
The fuel system includes the following compo-
nents:
•
Fuel Lift Pump
•
Fuel Filter
•
Vapor Separator
•
Fuel Circulation Pump
•
Fuel Supply Manifolds
•
Fuel Injectors
•
Fuel Return Manifolds
Fuel Lift Pump
The fuel lift pump is a mechanical, pressure-pulse
pump. The diaphragm of the pump is driven by
two pulse hoses that connect to the cylin-
der/crankcase assembly.
Fuel lift pump pulse hose locations:
•
Front mounted pump
: cylinders 3 and 6
•
Side mounted pump
: cylinders 2 and 5
Vacuum from the fuel lift pump pulls fuel from the
fuel tank. Once fuel reaches the pump, internal
pump pressure forces the fuel from the pump
through the fuel filter and into the vapor separator.
Fuel Filter
The water separating fuel filter protects the vapor
separator and the high-pressure components of
the fuel system from water and contaminants.
Refer to
on p. 74 for service frequency.
Vapor Separator
The vapor separator:
•
Serves as a water-cooled fuel reservoir to accu-
mulate incoming fuel from the fuel lift pump and
from the fuel return manifold
•
Contains a float controlling the venting of fuel
vapors
•
Contains a fuel pressure regulator for the high
pressure fuel system.
The vapor separator is serviced as an assembly
and includes the fuel circulation pump.
