    Help!
    I have replaced the pump and filled the tank after 2 years dry storage. I can manually pump fuel and petrol reaches the carburettor, if I turn the engine,  petrol reaches the carburettor, I have removed the bowl and cleaned the jets and cleaned the filters.  If I manually operate the pump she will start and run, but stops after a couple of minutes, she will start and run again if I manually operate the  pump, but she fails to run continuously, what do I do next please?,

    Sounds as though the “foot” of the fuel pump is not correctly conntacting the cam on the engine. Try removing the pump and reseating it. You should be able to feel the foot touching something as you put the pump back on.

    Hi Bruce

    when I turn the engine, fuel squirts out from the banjo joints, and when connected up and the bowl removed  I can get fuel through into the carburettor

    Well, that sounds as if the pump is operating correctly.The only other thing I can think of is the needle valve in the carb might be sticking , but then it wouldnt fill the float chamber when you hand primed ?? Maybe float sticking??

    I had a Morris Minor. Admittedly with an electric pump. Anyway it would pump fuel to the carb. I would drive off. After a while the car would splutter to a halt. It turned out to be rusty debris from the fuel tank almost but not quite blocking the fuel pipe. Maybe try blowing down your fuel pipe and see what happens.
