Ditto, On the hoses, but all the way clockwise is the drivers side tank and counter clockwise is the passenger side.
There should be a data plate on the floor that is marked the tanks.

so the long handle points to the tank thats being drawn from?

On my trucks the short end is the tank it's on. The long end is the handle to turn it.
But yours may be put on wrong.
