connector is supplied with a captive “tell-tale”
ring, the purpose being to hold the connector
teeth retracted. When the two halves of the
connector are pressed together, the ring is
ejected to show that the connection has been
successfully made. Fit the fuel pipe connector
clip (see illustrations).
56 As soon as the injectors and fuel rail are
installed and the fuel pipes are connected,
connect the battery and switch the ignition on
and off twice, without cranking the engine, to
pressurise the fuel system. With the system
pressurised check all disturbed fuel unions for
leaks.
57 Refit and reconnect all other removed and
disconnected components.
58 Reconnect the battery.
SOHC and 2.8 litre V6 engines
1 Disconnect the battery negative lead.
2 On V6 models, unclip the HT leads from the
fuel pressure regulator bracket.
3 Place a drain pan or plenty of rags beneath the
regulator, then disconnect the fuel return pipe
(see illustration). Be prepared for fuel spillage.
4 Disconnect the vacuum pipe from the
regulator (see illustration).
5 Slacken the fuel feed union nut (see
illustration). Wait until any residual fuel
pressure has decayed, then unscrew the nut.
6 Unscrew the nut from the base of the
regulator. Remove the regulator.
7 When refitting, only tighten the regulator
base nut lightly at first. Secure the fuel feed
union and tighten its nut, then fully tighten the
base nut.
8 Reconnect the vacuum and fuel return pipes.
9 Remove the drain pan or rags. On V6
models, secure the HT leads to their clip.
10 Reconnect the battery. Switch the ignition
on and off five times (without cranking the
engine) and check that there are no fuel leaks
from the regulator.
DOHC engine
11 Disconnect the battery negative lead.
12 Slowly loosen the fuel rail feed union to
relieve the pressure in the system. Be
prepared for fuel spillage, and take adequate
fire precautions.
13 Disconnect the fuel return hose from the
pressure regulator (see illustration). Again, be
prepared for fuel spillage.
14 Disconnect the vacuum pipe from the top
of the pressure regulator.
15 Unscrew the two securing bolts, and
withdraw the regulator from the fuel rail along
with the O-ring seal. Discard the O-ring.
16 Fit a new O-ring to the regulator, and
lubricate it with a smear of clean engine oil.
17 Fit both the securing bolts to the regulator,
then position the regulator on the fuel rail, and
tighten the securing bolts.
18 Further refitting is a reversal of removal,
but if the fuel return line was originally secured
with a crimped-type clip, discard this and use
a new worm drive hose clip.
19 On completion, check the fuel line
connections for leaks, pressurising the system
by switching the ignition on and off several times.
2.4 & 2.9 litre V6 engines
20 Disconnect the battery negative lead.
21 Depressurise the fuel system.
22 On models equipped with an aluminium
fuel rail and late level fuel pressure regulator,
remove the fuel return pipe retaining collar
from the top of the regulator.
23 On all models, place a suitable container
below the engine to catch any spilt fuel, then
disconnect the fuel return pipe and the
vacuum pipe from the fuel pressure regulator
(see illustration).
