A fuel tank is located either:

• at the rear of the car beneath the luggage compartment (Saloon and Estate)
• at the rear of the vehicle on the left hand side (Van)

The quantity of fuel in the tank is registered on the fuel gauge when the ignition is switch “on”. The gauge is designed to eliminate needle fluctuation whilst the ignition is switch on.

The fuel tank filler is located :

• to the right of the rear number plate (Saloon and Estate)
• to the rear of the van on the on the left hand side (Van)

The filler cap may be easily removed by turning it in an anti clockwise direction. Make sure that the filler cap is replaced securely and see that the vent hole is clear of obstructions at all times, otherwise failure of the fuel supply to the carburettor may result.

The engine is designed to operate on premium grade fuel. An optional low compression cylinder head is available should it be necessary to use low grade fuel.

Domed Cover Type
To service the domed cover type, remove the screw from the top of the pump and detach the cover and filter screen. Clean any sediment from the pump body. Clean the screen in petrol and replace it on the fuel pump body with the reinforcement upwards. Check the gaskets to ensure that they are in good condition and will make an airtight joint. Renew the gaskets if necessary. Refit the domed lid and tighten the screw.

Replace the glass sediment bowl and tighten the clamp nut

Check that there is sufficient fuel in the petrol tank.
Check that the filter screen and fuel pump have not become fouled with sediment.
Check that there is no air leak at any point in the fuel line connections, which would result in air being drawn into the system, so that the pump will not prime.

A comparatively simple test for fuel delivery can be carried out by disconnecting the fuel feed pipe to the carburettor, when a distinct spurt of petrol should be evident for every two revolutions of the engine.
Warning – Petrol is highly flammable. Please ensure you take suitable precautions if following Ford’s 50 year old advice.

All adjustments are made at the time of manufacture and, with the exception of the idling adjustment, will remain permanently correct unless disturbed. The idling adjustment should be checked after the car has been “run in”.

All petrol jets are accessible from the outside of the carburettor and they should be removed and cleaned periodically. Obstructions should be cleared by blowing through the jets and passages with a tyre pump.

On no account use wire or anything else which could enlarge the jet orifices, as the jets are calibrated to very fine limits and not only economy, but general engine performance can be upset by enlarging the jets in this manner.

The special two-stage starting device on the side of the main body must be used with care, as it is designed to provide a very rich mixture for cold starting, when the choke control is pulled right out. Great care must therefore be taken to follow the correct starting instructions, otherwise excess petrol will pass into the engine and may cause premature engine wear.

All adjustments are made at the time of manufacture and, with the exception of the idling adjustment, will remain permanently correct unless disturbed. The idling adjustment should be checked after the car has been “run in”.

The air cleaner used with this carburettor is of the wire gauze type, except on certain models where a paper element cleaner is fitted.

Note - On no account “pump” the accelerator pedal when starting the engine.

Idling adjustment must be carried out when the engine is hot as follow:-
Screw in the slow running adjustment screw until the idling speed is a little faster than normal.
Unscrew the volume control screw until the engine begins to “hunt”
Screw the volume control screw in again until the engine runs evenly. If the engine speed is then too high, unscrew the slow running screw until a reasonably slow idling speed is obtained. This may cause a slight resumption of “hunting”.
If so screw in the volume control screw until the idling is perfect.

Note that the volume control screw alters the volume of mixture passing into the engine. Screwing it in reduces the volume of mixture and screwing it out increases the volume.

It may also be necessary to make an alteration to the distributor timing, in order to obtain satisfactory idling.

Do not expect a new engine to idle perfectly at low speeds until various machined surfaces have had a chance to “run themselves in”.
