Idling a car for a few minutes 3 quarts low on a 7 quart system won't hurt. I've had many a car come in the shop 3+ quarts low on a 4 quart system and idle fine, driving is another story because that remaining 1 quart is sloshing around in there not being picked up by the pick up screen. As said earlier just overfill by 2 quarts, let the Accusump fill, then add the remaining quart.
