Introduction
I change the diesel filter every other oil change.

If your car is still equipped with it, remove the engine cover:
-
remove the staple
-
unscrew the screw on the side
-
remove the cover
-
-
-
Place a container under the car at the level of the diesel filter
-
open the tank bleed screw
-
and let the tank empty by gravity
-
The fuel in this tank probably contains a lot of water, which is why I do not recommend reusing it. It will be taken to a recycling center.
-
-
-
press the 2 tabs on the diesel outlet connector
-
and pull to unplug
-
This will create an air intake: the tank will empty much more quickly.
-
disconnect the small return hose
-
-
-
unlock the tank cover clip
-
move it aside very slightly
-
lower it and leave it on the tank
-
Be very careful, this clip is extremely fragile. It is easily found at Peugeot if you break it, OEM number 1904.26.
-
-
-
use a small flat screwdriver to pry off the cover
-
remove the cover
-
remove the filter
-
The filter I removed is very clean but I just bought this vehicle and had no service receipts on it.
-
-
-
clean the tank using a cloth and a blower if possible
-
Even if it is possible to do it, I strongly advise against disassembling the tank. The filter holders are a disease on DW8 and it is better not to touch them if everything works like here.
-
don't forget to close the bleed screw
-
-
-
remove the old o-ring using a small flathead screwdriver
-
install the new o-ring
-
check that it is in place
-
-
-
present the filter (it fits in quite naturally)
-
put it down
-
and press firmly to put it in place
-
-
-
oil the o-ring
-
I use new engine oil.
-
Place the cover in the correct direction and press into place
-
present the clip and lock it
-
-
-
connect the small hose to the cover
-
Operate the priming pump until diesel flows from the outlet
-
Provide a cloth.
-
connect the filter outlet hose (you should hear a "click")
-
-
-
operate the pump again until resistance is encountered
-
start the engine
-
check for leaks and turn off the engine
-
-
-
correctly present the engine cover
-
screw the screw on the side
-
install the locking clip
-
This cover is mainly aesthetic. If you no longer have it, it is not essential to buy one.

Hello, thanks for the tutorial which is excellent, I had to add diesel to the tank, nothing came out, maybe it would be good to suggest it. I also tapped the lid lightly with a hammer so that there was no air intake.
Thanks anyway it's great
Hello, your pump is PT hs. No need to fill the tank normally but you can do it. It will help to prime faster. First try to replace the priming system
Good morning,
I can't get the filter to prime again. I pump but nothing comes out.
Do you need to fill the diesel tank first?
Good evening and thank you for your comment. Concerning the hose, I advise you to go to Peugeot directly. I will not be able to make a tutorial because it will not be validated by Oscaro since the part is not available on the site. But I think it is not very complicated. You have to follow its path. Good luck to you.
Very good tutorial! Many do not do the purge to evacuate the air. Can you make a guide for changing the diesel outlet connection hose (the big one) because the 3 green seals inside have play and no longer do their job. also I can't find it on your site, where can I buy it?
