GENERAL
Use the B.U.D.S. software to release the fuel
pressure in the system. Refer to
FUEL SYSTEM.
WARNING
Fuel lines remain under pressure at all times.
Always proceed with care and use appropri-
ate safety equipment when working on pres-
surized fuel system. Wear safety glasses.
Do not allow fuel to spill on hot engine parts
and/or on electrical connectors. Proceed with
care when removing/installing high pressure
test equipment or disconnecting fuel line
connections. Use the B.U.D.S. software to
release fuel pressure prior to removing a
hose. 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 bilge. Fuel is flammable
and explosive under certain conditions. Al-
ways work in a well ventilated area. Always
disconnect battery prior to working on the
fuel system.
When the repair is completed, ensure that hoses
from fuel rail going to fuel pump are properly se-
cured in their supports. Then, pressurize the fuel
system. Refer to
FUEL TANK AND FUEL PUMP
subsection.
WARNING
Ensure to verify fuel line connections for
damage and that NO fuel line is discon-
nected prior to pressing the START button.
Always perform the high pressure test if any
component has been removed.
To check fuel rail for leaks, first pressurize the
system then spray soapy water on all hose con-
nections, regulators and injectors. Air bubbles
will show the leaking area. Check also for leaking
fuel or fuel odor.
WARNING
Thoroughly rinse an dry fu
el hoses from the
soapy solution after the l
eak test. Failure to
clean fuel lines from soap
might lead to fuel
line deterioration over
time.
WARNING
Never use a hose pincher o
nhighpressure
hoses.
