Oil inlet to boiler fuel pump leaking

I had my boiler serviced recently and for several days there has been a lingering smell of oil.  I eventually traced it to kerosene slowly dripping from the pipe inlet to the fuel pump (pic attached).  Just wondering what might have caused this - for example whether there is supposed to be a washer?  The nut appears properly tightened and there are no obvious ruptures to the fuel line or the pump..

    I'd call the engineer who serviced it. I had to replace the pump on mine. Looks like a Riello burner.

    Try nipping it up very slightly - it may well work, if not then yes, call an engineer

    Hi GF.
    You say "The nut appears properly tightened" - what do you mean by this? Have you actually applied a spanner to it, or are you just saying it doesn't feel loose?
    If you wipe it dry with a tissue, and then use a tissue corner to test, can you tell where the oil is coming from?


    When a seep appears at green, are yellow and orange both dry?
