Injector size??

[Wayne in NZ]

You would be best to on-sell your current system and use an HSF-3 system which will allow for a greater delivery of injectant.
The older ERL systems are limited to 330cc per minute and would not be enough for your engine.
Have a look around the Howerton Engineering or Aquamist sites there are flow calculation charts there to help you figure out how many cc per minute you would need.
My 2c worth.
