2. Discard gasket ring.
3. Wipe off any fuel spillage.
Fuel Pump Installation
The installation is the reverse of the removal
procedure. However, pay attention to the
following. Rotate fuel pump during
insertion as per removal procedure.
Attentions and Detection
FUEL SYSTEM
The fuel system of a fuel injection system
holds much more a pressure than on
carbureted vehicle. Prior to disconnecting a
hose or to removing a component from the
fuel system, follow the recommendation
described here.
Fuel lines remain under pressure at all times.
Always proceed with care and use
appropriate safety equipment when
working on pressurized fuel system. Wear
safety glasses. Proceed with care when
removing/installing pressure test
equipment or disconnecting fuel line
connections. Cover the fuel line connection
with an absorbent shop rag. Slowly
disconnect the fuel hose to minimize
spilling. Wipe off any fuel spillage in the
engine compartment. Do not allow fuel to
spill on hot engine parts and/or electrical
connectors. Never use a hose pincher on
injection system high pressure hoses.
Replace any damage or deteriorated fuel
lines.
When the repair is completed, ensure that
all hoses are connected and secured.
Always perform the fuel pressure test if any
component has been removed. A pressure
test must be done before turning the
ignition key to ON and setting the engine
stop switch to RUN. The fuel pump is
activated each time in these conditions.
To locate a leak, pressurize the system.
Check for leaking fuel or fuel odor. Spray
soapy water on all hose connections and
injectors. Air bubbles will show the leaking
area.
Inspect the fuel lines, fuel tank, fuel tank
cap for damage, clogging and leakage of
fuel. If any damages are found, replace the
defective parts with the new ones.
Use a special tool to tighten the oil pump
cover with a torque of 75N.M; after
tightening, visually inspect or check the
base gasket by hand to ensure that the
gasket is not folded or damaged.
FUEL PRESSURE TEST
The pressure test will show the available
pressure at the fuel pump outlet. It validates
the pressure regulator, the fuel pump and
leaks in the system.
