Description
Fuel is pumped by a diaphragm pump to the carburettor 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
adjacent to the fuel tank. The float operated sender unit in the tank
actuates the fuel gauge situated in the fascia.
The carburettor is an SU type HS2 conforming to the department of
the environment vehicle emission regulations.
Air drawn in to the carburettor is filtered by a dry paper element air
filter.
Routine maintenance
The carburettor dash pot in the suction chamber requires topping up
every 3,000 miles (5,000 km) (Figure 1).
The air filter element should be checked every 6,000 miles (10,000
km) and replaced at 12,000 mile (20,000 km) intervals.
The in-line fuel filter should be renewed at 12,000 mile (20,000 km)
intervals.
Operation 1 Fuel tank - removal and replacement

mounting studs. take care not to damage the mounting stud threads.
10. Carefully lower the tank, disconnect the sender unit and
remove the fuel tank from the car.
Re-assemble in reverse order.
Operation 2 Fuel tank sender unit - removal and
replacement
If faulty readings are suspected on the indicator gauge check the
indicator and sender unit as follows:
1. Remove the fuel tank a previously described in Operation 1 .
2. Twist the sender unit locking ring to release the unit from
the tank and withdraw the sender unit.
3. With the sender lead disconnected, turn on the ignition and
the gauge should read empty.
4 . Now touch the lead to ground and the gauge should move
to full. This will confirm that the gauge and circuitry is working
correctly.
5. Reconnect the sender lead to the sender and earth the
body. Manually operate the float lever. With the float at the bottom
the gauge should read empty. raising the float, the needle should
smoothly move to full. Any deviation from these readings will confirm
that the sender unit is faulty and will need renewing.
