25320277 - Fuel filter

The fuel filter is located just in front of the rear nearside wheel – you should be able to get to it with

the car on the ground, but jacking it up at the back and supporting on axel stands makes the job a lot

easier.

Step 1

Firstly, depressurise the fuel rail

– somewhere near the injector

rail is the depressurisation point:

it looks like a big tyre valve cap

(shown circled on the photo of

a 2.2 engine).

You may have to remove the

engine cover to find it!!!

Unscrew the cap carefully as the

rubber seal inside can

sometimes fall out and

disappear into the depths of the

engine!!

Then depress the centre pin on

the valve to release the

pressure. Some petrol will come

out, so use a clean absorbent

cloth to catch it and prevent it

going all over the engine.

You will need to press the pin a few times to ensure the fuel system is fully depressurised.

When done, refit the cap (making sure the rubber seal is located correctly)

Step 2

With the fuel system depressurised,

locate the fuel filter and undo the small

Torx screw (circled red) which holds

the filter to the underside of the car.

Then gently prise the filter from the

bracket – this should then give to

enough slack to get at the pipe clips.

Doing one side at a time, push the filter

into the pipe a bit to relieve the tension

on the clips (blue square), and depress

the 2 “wings” - one on each side of the

clip - to release them. And the pull the

filter from the pipe. Be prepared for

some petrol running down your arm!!

If you’ve got strong fingers you should

be able to do this quite easily, but

failing that use two small screw drivers

to push in the wings nearest to the

filter. Repeat for the other side.

Step 3

Now, using a small screw driver,

carefully swap the clips from the old

filter to the new one – making sure you

refit them the correct way round.

Then simply refit the new filter to the

fuel lines (making sure that it is fitted

the correct way round) - it simply

pushes in to the pipe until it clicks.

There is a flow direction arrow on the

filter to help you.

Finally, refit the filter to the bracket

and tighten the Torx screw.

Then turn the ignition on for 5-10

seconds to re-pressurise the fuel system

Job done!!
