Remove the metal bracket ontop of filter, 2* 8mm blots. Flat head scredriver and gently prise the electrical connector off. There are two fuel lines ontop of the filter housing, the 1 on the right hand side push the 2 white clips in and pull off othe fuel pipe can be left on. Then hold the top of the housing in place and screw the cap off and remove old filter. The new filter soak with diesel, remove the little white cap on the filter and fill up the filter housing, now insert the filter remember to add the new seal also. hold in place the top of the filter housing and screw the cap back on, reconnect the fuel pipe and electrical plug. Now you need a 8mm plastic pipe approx lenght 2ft, on the back of the cap you will find a nipple, push pipe on and start sucking/ using a siringe i had to do this for 8-10 mins until most of the air is out...... Now turn you key so light on on dash board do this for 15 secs, 4 or 5 times whilst pushing down on throttle.... Then start cranking over may take 5 mins or so but it will start and kick a load of rubbish out.......

Or instead of sucking the air/fuel out you can also syringe fuel in the bleed screw too. Took me a lot less than 8 mins.

Changing the fuel filter won't affect your mpg, might help the car run better though if the old one was clogged and restricting flow

Last time I did this I had a nightmare getting it started!! Even with a hand priming pump!!

Had to suck the fuel thru the various stages in the end...

What else have you changed?
Changing the air filter for example will affect the mpg as for the same amount of fuel you are using more air = a bigger bang...

Did you use a genuine filter/seal? Heard a few stories about aftermarket filters being a nightmare for some reason

It's certainly a very good increase and your car must be feeling better! Does it feel better to drive?
I'd put It down to the general service and air filter change though.

feels alot more responsive, escpecially on pull off and when the turbo kicks in, before when i thought it was ok, now i know it struggled quite a bit. the fuel filter what was taken out was full of crap and very very badly discoloured, the air filter which was ment be a kind of bright yellow, when taken out was black, literally black with leaves and all kinds of crap in there. the oil and filter was no better. it has a fram air/fuel filter fitted, mobil 1 oil and k&n oil filter now.....
