  Remember, you are also dealing with about 1/2 " of block height/deficit for the 1.6 which I think also means 1.9 lines are a different length, and so a different injection phase at higher revs compared with 1.6 lines...
  
  Can lines not be annealed prior to rebending?
  

  
  Correct, this is a 1.9D engine / taller block and am putting on a 1.9D pump and 1.9D injectors so all 1.9 parts in essence.   And yes, the 1.9 lines are likely a little different in length than the 1.6 lines, thus the best setup is to run all the lines the same length, so all 1.6/re-bent or all 1.9 w/ stock bends. 
  
  Suppose the lines could be annealed and re-bent.  I have also heard that the 1.6 lines on a 1.9 engine just barely fit, but then adding the longer 1.9 pump sort of stretches the 1 / 2 lines a bit too far, plus the interference at the top of the pump.
  

  I really must reread the threads I post to more thoroughly! I missed the engine size, or read what I wanted to.
  Are your injectors the dual spring types? I have a set bought in error that I may try out on my Quantum, if the 1.6 injector lines will reach.

• Not sure on the injectors, probably be a week or more until I see them.  They are supposed to be the right p/n for the 1Y engine (068130202F).  Since the 4 injectors I have in the engine now are of unknown age and condition, figured now is the time to change them out.  So easy to work on that part of the head with that pump out of the way. 
  
  Can't wait to get all the new parts in and fire it up.  Will be the first time that this engine will have the proper set of equipment on it, since it has been running on old 1.5 or 1.6 injectors and pump for 10+ years.

• New injector "pipes" arrived from Germany on Friday.  Quick test fit and they go on w/o any modification.  Loads of clearance at the top of the pump:
  
  
  
  In comparison, the old 1.6 pipes interfered at the top of the pump:
  
  
  
  #1/#2 lines are way different shape:
  
  1.9D:
  
  
  1.6D:
  
  
  Was unable to source the 1Y injectors, but did score a set of new 1.6D injectors to put in, same 130 bar break pressure.

• im not canadian so i don't really know, but i thought that only some 1.9s  came with the dual spring injectors

• I think Danster might have 1Y used injectors up for grabs.

  I've swapped the long and short delivery valves on several pumps without issue other than needing to adjust the max fuel.
  

  
  Might be what Giles is referring to:

  pls do not start swapping internal/external parts from your other pump,  you will change all my
  settings for the fuel delivery.

  
  Suppose on a stock pump, may not be that big an issue.
