Third test :

Switched to see spray pattern difference from the last tests of Ford SVO 30 red tops, which in a Corvette are 36 lb/hr
to these GM fuel injectors for the C5 Z06 which are 28 lb/hr

Being these have not been used for 10 plus years, I had them in the ultrasonic cleaner for about 20 minutes with the tester
pulsing the On times on and off
