Todd.....it depends upon what bilge pump you put in.....they run from
something like 200 to 600 gallons per hour. I have a 360gph which seems
about right wrt not pushing it in too fast but fast enough that I can fill
each wing in around 5-10 minutes (9lbs vs gross).

Also I wanted to note that the tank fits in the back end of a Ford Explorer
or Expedition with all the seats up and with room to spare and does not
require a truck.....at least if you are in the US. I know that some
countries are more conscientious re fuel economy and therefore have smaller
vehicles and so it would not fit in a Mini for example!
