when I do one of these i remove the pipes and fit a rubber grommet over the pipes to seal them,when fitting the abs unit fit the outlet pipes first then the inlet,make sure the master cyl is topped up,tighten the inlet pipes and slacken each outlet in turn until you get a flow of fluid from each one and let gravity do the job for you,have never had to bleed a system yet,if you cant get a pedal then you will have to go to each wheel in turn and with someone to help bleed each wheel usually starting farthest away from the abs unit
