Fuel Injector to Paint Ball Cannon 1

[triage]

Am building a science project with my son, and our intent is to use a filled dive tank as source for compressed gas, to make a paint ball cannon. Our hope is to use an automobile direct fuel injector as a solenoid controlled valve that can be purchase at an auto parts store.

I can not locate specs on injectors, can anyone direct me to specs on injectors, for pressure rating, response time, flow rate?

Is there an auto injector which can actuate 3000 psi?

Any help is appreciated
