You have to repeat this process severals times to really get the tank full. You can imagine that the amount of air trapped in the vent is highly variable...
There's the filler pipe down to the tank, with another line or two ventilation lines from the top of the tank to the large filler pipe, and one line from the ventilation line to an expansion tank up front. There's no vent tab so the amount per fill can probably vary quite a bit.
