fuel filter question

[331 stang91]

It seem that my fuel filter was on wrong from the previous owner. I'm surprised the car ran ok. Anyone else ever have this happen? By wrong I mean the flow arrow was pointed towards the tank.

Never seen that but I would proll change the filter. That might have blown the element out of place.

I did change it thats how i noticed. I wounder if it really matters which direction it goes in? Anyways its in the correct way now.

I can't imagine it not mattering, otherwise why show the flow direction? Maybe the previous owner just accepted lousy performance or never went WOT.
