INSTALLA TION
Review the high pressure fuel system warning before
beginning repair (Refer to 14 - FUEL SYSTEM - WARNING)
WARNING: NO SPARKS, OPEN FLAMES OR SMOK-
ING. RISK OF POISONING FROM INHALING AND
SWALLOWING FUEL. RISK OF INJURY TO EYES
AND SKIN FROM CONTACT WITH FUEL. POUR
FUELS ONLY INTO SUITABLE AND APPROPRI-
ATELY MARKED CONTAINERS. WEAR PROTECTIVE
CLOTHING.
CAUTION: There is a special tightening procedure
for the fuel rail solenoid that must be followed
along with the proper use of a torque wrench.
Therefore the fuel rail must be removed before
installing the fuel pressure solenoid. Attention must
be paid to the sealing ring before assembly. If the
sealing ring is damaged when assembling, this
could result in a not so visible leak.
NOTE: Observe the alignment of the pressure sole-
noid. The electrical connection must point in the
same direction as the connection of the injection
line at the fuel rail.
