    Last night my car lost all power when driving about 30 miles from home on a straight dual carriageway.
    It will tick over fine and accelerate initially but won't maintain a constant speed.
    We managed to get home by pulling the choke out fully and hobbling along at 25mph in fourth gear.
    Every time I changed down for a roundabout or traffic lights the engine stalled, but would fire up immediately afterwards.
    Tried it again this morning and it seems to have the same problem within a mile.
    Has anybody experienced this issue and can you point me in the right direction for a fix?
    I'm tending towards fuel starvation, maybe the fuel pump.
    The engine is a 2L Ford Pinto with twin webber carbs.
    Thanks

    Electrical or mechanical fuel pump? Any sign of fuel leakage under the carbs?

    Which ever fuel pump you have electric or mechanical you need a new one, also remove the pick up pipe from the tank and check the filter, in the past there has been fuel tanks overly plastered in gasket compound which tends to fall off from wherever it was applied and clog up your pick pipe and its filter.

    Carb float needles sticking, or as suggested blocked filter/ faulty pump.

    I had exactly this problem with the cabrio except the offending sealant had managed to travel down the fuel line and was built up just before the inline filter which allowed the motor to run at low revs but any application of throttle caused the motor to die as soon as the float bowl was empty. fixed it by removing fuel lines from tank and filter and blowing through with an air line. might be worth a ckeck.

    Take off the inlet pipe to the carbs with the bowls full and
    run the engine.This will test the pump/filters and all the fuel
    system up to the carbs.If you don't have a good flow the problem is there.
    If it flows well it is the carb end of the system.

    Thanks for all the advice. I will try everything and report back on success (or otherwise).

    I have ordered new fuel pump, hose and filter (the originals may be 35 years old) and will fit them in the next couple of weeks.

    It is a mechanical fuel pump, by the way.

    Check also that the spring under the diaphragm is ok, not weakened or broken.

    With my old classic I fitted a solid state pump next to the tank and made a blanking plate to fit over the mech pump hole in the block so the old pump was eliminated. Cured forever the dreaded vapour lock. Modern fuels evaporate much more easily than the old stuff so fit one of these and forget. Peter.

    Fuel generally leaks past the diaphram if it is perished and then gets squirted out of the ventilation holes in the pump leading to a very strong smell of petrol.
