2008 2.2 Relay Fuel Filter Change

[carl13671]

Hello all,

Im thinking of changing my fuel filter,,is there anything I should know?

Ive been advised to remove the complete housing off the bulkhead as they can be tight to undo.

 

Any advice appreciated

This is based on Citroen's procedure and it includes removing the complete filter housing before removing the top.

 

2. Removing

Disconnect the battery. (this might not be necessary)

Remove the front protection under the engine.

 

Pour the diesel filter bowls cleaning product index "N3" into the cleaning tray (if being used to clean out the filter bowl).

Clean the unions of the 2 pipes on the fuel filter Using a paint brush .

CAUTION : Plug the orifices when uncoupling a pipe ; (plugs are probably supplied with the new filter element)

Uncouple and then plug the 2 pipes. (these might have a coloured tab that needs pushing in to release the pipes)

CAUTION : Plug the ducts on the fuel filter.

Unplug  The electrical connector(s) on the filter

Unclip the fuel filter assembly (towards the top).

Remove the fuel filter.

 

Mark a reference on the top ring between the references on the top and filter bowl.

Loosen the top ring - Using a pipe wrench (on a workbench).

Remove the filter element.

3. Cleaning the fuel filter

Pour the diesel filter bowls cleaning product index "N3" into the cleaning tray.

Clean the fuel filter bowl  (Using a paint brush) and then drain the fuel filter.

Dry and wipe the fuel filter  Using a lint-free cloth (available from Replacement Parts).

4. Refitting

CAUTION : Open the sachet containing the new filter element just before refitting.

Fit the new filter element .

Tighten the top ring until the marks are aligned ; Using a pipe wrench.

Refit : The fuel filter.

Connect the electrical connector(s)

Remove the plugs.

 

To bleed air out of the filter and fill it, it is suggested to connect up a pipe to bypass the fuel return but this is probably not needed and I did not need to do this on our C5 but it has a priming hand pump/bulb.. 

 

CAUTION : Perform the operations to be carried out following reconnection of the battery (if the battery was disconnected).

Reconnect the battery.

Switch on the ignition 10 times in succession without starting to prime the fuel circuit. (it may be necessary to repeat this)

 

5. Bleed procedure / Checking for leaks

Start the engine.

Check the absence of leaks.

CAUTION : Declutch and accelerate fully at the same time for 3 minutes.

N.B. : The engine speed is limited to 2500 rpm in clutch anti-centrifugation strategy and the fuel pressure is regulated.

Check the absence of leaks.

Carry out a road test.

Check the absence of leaks.

 

 

Refit the protective shield under the engine .

UPDATE

 

All went well,

I was surprised how easy it was,the hardest bit was disconnecting the pipes.

I took the whole housing off the bulkhead and twisted it and it was only hand tight.

Filter has a hole in the side and the fluff was poking through.

The cutting out problem I originally had has now stopped.

Result :) :)

Citroen pipes usually have coloured tabs in them which should be pushed down whilst pulling the pipe off.
