Bleeding Ford Cargo 0813 Deisel Engine?

Hey guys, i have recently started renovating my horse box.
i found a diesel leak on the diaphram valve (of which has now been replaced) how do i bleed this system properly. i have done what i thought,
hand prime up to the diaphram, loosen off the injectors, crank her over, but i am not getting any diesel upto the injectors, is there a bleed bolt i am missing somewhere?

cheers guys if you can help.
