Fuel system

Description
Fuel is delivered
to
the carburettor by a
camshaft operated diaphragm pump from a
rectangular fuel tank mounted under the floor at
the rear
of
the vehicle. The fuel is filtered by a
gauze filter located on the pick-up pipe
of
the
sender unit
in
the tank. The float operated
sender unit actuates the fuel gauge on the
fascia.
A downdraught carburettor is used incorporating
a diaphragm accelerating pump and a
depression operated economy device.
Vehicles built after September 1973,
will
have
a carburettor that conforms
with
the Department
of
Environment Vehicle Emmission Regulations.
Early vehicles have identical carburettors
with
the exception
of
modifications made by the
manufacturer
to
conform
with
the Regulations.
The carburettor is a
30
IZ or
30
IZE model, the
latter being the emission controlled type.
Air
is filtered through the carburettor by a
dry
paper element type air cleaner that also serves
the engine oil
filler cap.
