.



I pulled these from my TBI and need to know what size they are. They have no markings or other numbers besides what's shown in the pics. RIN-1001 on each injector, and 5319 on one and 5258 on the other.

These injectors appear to be a 'gray' aftermarket origin - most likely Chinese knock offs. As to their specifications - it is anyone's guess. Send them to injector service for testing - they can tell you what they are.

Good luck

Thanks for the information. I think I'll just try to find some stock or rebuilt 350 injectors.
