The way you do it is take the fuel rail out, put a towel underneath all of the injectors, then go inside the car and put the key into ACC but do not start it.
That will pressurize the fuel rail and it will squirt out if your O-rings are leaking.
In your case it might just be emanage because like you said it only happens on decelerations.
