6.7 Slackening pressure release bolt to
depressurise fuel system - non-catalyst
system
prevent any undue strain being placed on the
fuel pipe (see illustration).
8 Once all pressure has been relieved,
remove the bolt and inspect the sealing
washer for signs of wear or damage and
renew if necessary.
9 Refit the bolt and washer to the fuel pipe
and tighten it to the specified torque wrench
setting whilst using a spanner to counter-hold
the pipe boss, to prevent the pipe or filter
being damaged.
7 Fuel system - pressure check
1 The following procedure is based on the
use of the Rover pressure gauge and adaptor
(Service tool numbers 18G 1500 and
18G 1500/3).
2 Depressurise the fuel system.
3 Unscrew the pressure release bolt and
screw in the adaptor, then connect the
pressure gauge.
4 Turn the engine over on the starter motor.
The pressure should reach the specified

value. Stop cranking the engine and watch the
gauge. The pressure drop in the first minute
should not exceed 0.7 bar.
5 If the pressure first recorded was too high,
renew the pressure regulator, which means
renewing the complete injector housing
assembly.
6 If the pressure first recorded was too low or
if it falls too quickly, check the system
carefully for leaks. If no leaks are found, check
the pump by substituting a new one, then
recheck the pressure. If the pressure does not
improve, the fault is in the pressure regulator
and the complete injector housing assembly
must be renewed. If this is the case, it is worth
dismantling the regulator to check that the
fault is not due to its being jammed open with
dirt.

removal and refitting 3
Removal
1 Remove the fuel tank.
2 Release the clips securing the tank vent
hose to the fuel tank breather and fuel cut-off
valve, then disconnect the hose. Undo the
vent hose and valve retaining nuts, then
disconnect the vent valve hose from the fuel
pump and remove the vent hose and valve
assembly from the tank (see illustration).
3 Disconnect the wiring connector from the
fuel pump.
4 Slacken and remove the six fuel pump
retaining nuts. Carefully withdraw the fuel
pump assembly from the tank and remove
the pump seal.

3 Work back along the cable outer and
release it from any retaining clamps.
4 Working inside the vehicle, undo the five
right-hand lower facia panel retaining screws
and remove the panel.
5 Release the cable from the upper end of the
accelerator pedal and withdraw the cable
from the engine compartment.
