That should not be too hard. You fill the 3 l tank and empty it in the 5 l tank. Then you fill the 3 l tank again and empty it in the 8 l tank. Then you repeat the operation, but this time you empty the 3 l tank in the 5 l tank until you fill it (2 l) and then in the 8 l tank (the remainder, i.e. 1 l).
This way you will have a full 5 l tank and 4 l in the 8 l tank.

Iraq just bought 10,000 surplus septic tanks and once the figure out how to drive them are counterattacking.
