"Spill timing" it's called, where I come from. You remove the injection line and delivery valve for the #1 cylinder, set the crank at the specified timing (24ºBTDC, in this case), apply fuel pressure to the feed port on the injection pump and turn the pump until the #1 fuel fitting just stops dripping. This indicates that the #1 pump element fill port has just closed and injection on the #1 cylinder has started.

yea spill timing,,sorry,i figured  that is the deal. ill just hook up a "new" inlet,and outlet line,with an electric pump in there . i sort of have a "rig" for that setup,,sweet!!! shouldn't be a big deal then :D
