When I bought my Magnette it was in a sad state.  It had an AC fuel pump mod=
el number=20
12V -EP 12. The pump is a good looking aluminum casting. I have always wante=
d to have it reworked.  (I don't know if it works or not .  Just assume that=
 with the rubber parts would be shot.)
I also have a SU fuel pump gotten with some other bits and pieces marked BMC=
 factory approved rebuilt #4080.  Anyone know where the bits to repair the A=
C pump could be found? =20

    Water in the carbs can cause this. A slug of water lies in the fuel
    transfer passages in the carb - when it gets sucked up to the

    Your comment that the filter is of unknown age but is OK is wishful
    guesswork - change it. And when you remove it, bang it on something
    with the inlet end downwards - see if any water comes out. Water
    does not go through good filters easily, but it can under some
    conditions, and it only takes about a half cc to block the jet as
    described. <br>
    (banging the filter like this can get you home when water blocks the
