DIY Fuel Filter Question

I have an early (9/99 build) e46 with the M52TU (2.8 liter engine). It has the simple and cheap fuel filter with NO internal regulator on the front end and only two ports, one in the front and one in the back.

The Bentley Manual shows the arrows on the filter pointing forward towards the engine. When I pulled the cover and looked at my filter I saw that the arrows pointed rearward. Is this possible? Has anyone seen a filter installed with arrows pointing aft? I've seen some posts that say the engine won't run if the filter is in backwards. I've never seen one with the fuel flowing through the filter back toward the tank.
