Fuel Filter - Which direction?

[Garn]

I am replacing the fuel filter on my 2007 LS . It is in back behind the back panel. I pulled the old one out but I made the mistake of not looking in which direction the arrow was pointing on the old filter. So now I don't know which direction to point the new one! Any suggestions?

Arrow is direction of flow, so point to ward engine.
