It's pretty easy, essentially just pull hoses off, replace filter, reconnect - and no you don't need to bleed it.
You'll need some pliers or molegrips to release & hold the spring clips on the hoses while you remove them. I usually just move the clips up the hose a couple of inches and them move them back down again when the hoses are connected to the new filter.
You might find it a bit fiddly sliding the old hoses off, might take a bit of twisting to & fro before they'll slide off, sometimes some careful levering on the ends of the hoses with a screwdriver helps, but reassembly should be a bit easier as there'll probably be a bit of diesel on them which helps them slide on.
Have a few bits of rag or kitchen roll handy to mop up any small diesel spills when you pull the pipes off. And maybe a carrier bag or two to put the old filter straight into. I usually put the old one inside some poly bags then in the box that the new filter came in. Don't lay the old filter on it's side as it'll be full of fuel and it'll leak out.
If there's a water drain on the bottom of the new filter, make sure it's fully tightened.
Not sure on your exact car, but of the 4 hoses, you might find 2 connect into obvious inlet/outlet nipples which you just pull off, but the other 2 connect into a sort of round plastic tee piece, which is clipped down into the top of the fuel filter.
If you've got the plastic piece, leave the hoses attached to it, but pull out the obvious retaining clip on top (don't let it ping off and lose it in the engine tray!), then just lift the plastic thing up out of the filter. There are a couple of rubber o-rings on it, if your new filter comes with new o-rings, replace the old ones. Then as all good manuals say - "refitting is the reverse of removal"
Restart the car, usually it'll start up OK but you might get a bit of brief chugging while any air comes through.
Of the 3 or 4 I've changed, only once did the car stop and take some cranking on the starter before the air bled out.
