Not 100% au-fait with the workings of the Bosch pumps (although suffice it to say I'm liking them very much more than Lucas at this current moment ! ) but I think you could be right the fuel screw could have been backed off too far. For the time it takes to move the arm and play with the screw it's got to be worth a shot anyway.
