Okay, so im gna write a guide on how to change the fuel filter on a 1999 1.5d. I had so much hassle trying to find the fuel filter on a diesel, finding out how to do it and all sorts so here ill write everyhting i can to make it easy for anyone else who might want to do this.
things youll need:
new fuel filter (bosch)
gloves
oil
diesel
couple of small spanners ( dont know what size just .. smallish ones)
plastic bag ( no holes in it )
clean rags
1) first you will need to make sure you have the correct filter. it will be a screw on one with an air release tap at the bottom. i got mine from euro parts and they matched it with my reg.
2) you will need to remove your battery and battery rack using one of the small spanners, remove the nuts and just pull the battery rack off. easy. then undo the bolt holding the air filter housing in place and jsut fold that back out the way. the fuel filter will be located just to the left of the battery on the engine. it will look like its upside down
3) now youve identified it, put your gloves on and push the plastic bag under the filter around it. so now you have something the catch the filter a diesel when it comes off. you cant use a bowl or anything as there isnt enough room. (sorry for crap pic but like this
)
4) now you will need to undo the filter by turning it right. ... yes right. the thread on these are reverse for some reason ( bloody french ) and i found out the hard way by trying to turn it left and very nearly lost the tread to the part it screws onto. so turn it tight and it should undo by hand. if not then may need some influence .. jsut improvise

6) get your new filter, rub abit of out around the rubber seal and fill up with diesel about 3/4 full. then tighten it by hand. ( dones not need to ba any tighter than hand tight. the oil will prevent any leaks.
7) now thats its on it should look like this:
8) get your clean rags and just wipe away any diesel that may have escaped... its worth thorough cleaning as it is flammable and dont want any getting hot!.
9) now you need to get rid of any air bubbles in the system. so in a diesel you will have a grenade looking primer like a small black pump. you will need to pump this a few times untill it becomes quite full. once full, put some clean rags under the filter and slowely loosen the air release screw on the bottom of your new filter, this will release any air bubbles. repeat this a few times to be safe
10) now connect up your battery and try starting the car, it may not start or keep cutting out for a while, this means you still have air in the system so jsut continue to repeat the grenade process a few times.
11) once you know your car is runnning safe. turn it off, replace the air filter and battery rack and battery then turn the car on and leave it running for about 15 mins for it to clear itself and get use to the new filter.
12) doiuble check the filter make sure there are no leaks in the housing and make sure your air release screw is nice and tight ( dont want any air getting in while driving )
now you should be on your way
this is a job that seems to be under estimated alot and must be carried out with care and attention. it can potentially be dangerous and be safe, wear gloves and you should also wear goggles too! however, it is a very easy job to do and your car will benefit alot if done properly. the fuel filter should be changed every 50000 miles and it will help to maintain a clean and healthy engine.
p.s. been corrected, as manyslover70 correctly said, it isnt an "air release tap" it is infact a water drain point if you like the correct term
good luck guys, thank you
