It's not likely that one of the high pressure fuel lines
got clogged. Fuel
goes through one or two filters before getting there, a very sensitive pump
and the pressure is really, really high. Lower fuel
flow on that one line
could indicate there is still air in the system working its way out. Is that particular line
I had an universal XP-25 on a previous boat and I don't remember having to crack injector lines
to bleed the system. Matter of fact, there were some who advocated leaving one of the bleeder knobs openned all the time, so it was a self bleeding system.
