Can't prime Yanmar 2GM20

I did a service on my Yanmar diesel on the weekend (including fuel
filter) and now can't seem to prime it. I've followed the
instructions in the Yanmar manual and although I can get fuel flowing
through the fuel filter bleed valve via the manual fuel pump lever, I
can't seem to get it to 'bleed' beyond the fuel injection pump. I
repeatedly pump via the manual handle but nothing seems to come
through.

I tried turning the engine over as I thought it might be an issue with
the 'position' of the fuel injection pump but this did not seem to
make a difference.

Did you fill the new fuel filter with clean fuel before reinstalling
it? If not, that's your problem. Also, lubricate the rubber seal on
the new filter with clean fuel before you install it.

You will not normally be able to bleed fuel on the output side of the
injection pump without cranking the engine. Back off the nut on one
of the injection lines going to the cylinders, crank the engine while
you watch and see if fuel is coming out. If not, re-bleed the input
side of the injection pump and try again.
