Injector Duty Cycle

This may seem like a dumb question but I have been unable to find the answer.

Compact GM TB injectors

Hi
I am looking to use compact GM injectors. The only info I can find is a number on them. 5276. They are from an early 80s Nissan Pulsar or GM Holden Astra.
Does any one have any specs on them . They are low imp but thats all I know. What flow and pressure is what I need.
