anti-freeze in injector hole

Before installing injectors, we sucked out the back injector hole and looked like antifreeze was in the suction tube. Is it normal after sitting for 2 weeks waiting for the new injectors to find a bit of anti-freeze in there?

You sure it's antifreeze and not diesel if it's antifreeze then you might have a cracked injector cup.Take a good look at that cup with a bright light

You can still run the test see if it holds pressure .. If its leaking , you will end up with fuel in the de gas bottle ...
