Fuel filter on a 3.2

Hi all,

I was doing antiroll bar bushes and spotted it next to the tank. Got to thinking "hmm has it ever been changed?"

So just wondered does any one know how often it should be changed?
Looks fairly simple as you have them inline clip things, but will it need bleeding or anything like that?

Thanks
