air charge temperature sensor mounted in the
base of the air cleaner body, and disconnect
the breather hose from the camshaft cover.
Refitting
9Refitting is a reversal of removal, ensuring
that the disturbed hoses are securely
connected.
Refer to Chapter 1, Section 36.
Removal
1The fuel pressure regulator is located on the
left-hand side of the engine compartment
(see illustration).2Disconnect the battery negative lead.
3Identify the fuel hose locations, as an aid to
refitting. Note that there are three hose
connections on models without a fuel flow
sensor unit, and two hose connections on
models with a fuel flow sensor unit.
4Disconnect and plug the fuel hoses.
5Remove the two securing screws and
withdraw the regulator.Refitting
6Refitting is a reversal of removal, ensuring
that the fuel hoses are correctly connected. If
the hoses were originally secured with
crimped type clips, discard them and use new
worm drive clips.
Removal
1On SOHC models, the vapour separator is
located on the left-hand side of the engine
compartment. On CVH models, the vapour
separator is located on the right-hand side of
the engine compartment (see illustrations).
2Disconnect the battery negative lead.3Identify the fuel hose locations as an aid to
refitting, then disconnect and plug the hoses.
4Remove the two securing screws and
withdraw the vapour separator.
Refitting
5Refitting is a reversal of removal, ensuring
that the fuel hoses are correctly connected. If
the hoses were originally secured with
crimped type clips, discard them and use new
worm drive clips.
Mechanical pump
1On SOHC engines, the fuel pump is located
on the left-hand side of the cylinder block,
next to the oil filter. On CVH engines the fuel
pump is located on the rear right-hand corner
of the cylinder head.
2To test the pump, disconnect the ignition
coil LT “-/1” lead to prevent the engine from
firing.
3Disconnect the outlet hose from the pump,
and place a wad of rag next to the pump
outlet (see illustration). Take appropriate fire
precautions.
4Have an assistant crank the engine on the
starter motor, and check that well-defined
spurts of petrol are ejected from the fuel
pump outlet. If not, the pump is faulty.
Dispose of the petrol-soaked rag safely.
