How To Change A Fuel Filter On A 2.8jtd

Hi

Just found this site.

My motorhome based on a 2004 2.8jtd has now done 16000 miles and i want to change the fuel filter. In the old days of changing a filter on a BMC engine the fuel system had to be bled which could be a pig.

Could someone please tell me in simple stages how this is done.

Any help would be appreciated.

Steve & ann. --------- teensvan.

First make sure the ignition is turned off

Remove the air filter housing top.

Remove the air filter element itself from the housing - this can be
a tight squeeze.
Remove the 3 retaining nuts at the bottom of the housing & the 2 x worm
clamps from the housing to the snorkel & the engine breather &
remove the air filter housing from the engine bay to allow access
to the fuel filter.

Loosen the 2 bolts holding the fuel filter bracket to the firewall
enough to allow a oil filter remover tool around the filter or if
you can loosen the filter by hand you may not have to loosen the
bolts but I found it easier to loosen the bolts as it too close to
the firewall otherwise.
Then disconnect the wiring plug for the water trap sensor from the
bottom of the filter as this will have to installed on the new
filter
Unscrew the filter keeping it upright so as to minimize spillage of
diesel - empty the fuel from the filter into a container.
NB:
If you are satisfied that the container is clean & no contaminates
enter the excess fuel you could reuse this fuel to refill the new
filter or use new fuel
.

Remove the plastic plug which is threaded into the bottom of the
new filter & thread the water sensor into the new filter making
sure the "O" ring is correctly installed in the new filter.

Once the sensor has been installed then hold the new filter upright
& fill it right to the top with fuel, might take a couple of mins to fill properly
as it is absorbed by the filter paper itself just let it settle then topup if necessary.

Then holding it in that position to minimize spillage again refit
it to the firewall bracket & tighten - reconnect the water sensor
wiring plug & tighten fire wall bracket bolts.

Refit the air cleaner housing & tighten the 3 x nuts inside & refit the
snorkel & breather hoses to the housing & clamps & tighten same.

Refit air filter element & cap to housing

Make sure there is no background noise - kneel next to the drivers
door so you can hear the fuel pump working in the tank & turn the
ignition to "mar" ( do not attempt to start the engine ) for 10-15
secs then off - now you should hear the pump self bleeding the air
from the fuel low pressure side
Do this 2 to 3 times until you no longer hear the "farting" air
bubbles noise & there is a constant noise from the pump meaning no
air in the system - Job done!

You can then start the engine.
Thanks Davesport, Emile thanked for this post

Re: How To Change A Fuel Filter On A 2.8jtd

Hi
I think the procedure would be the same for the 3.0 but the difference is the 3.0 fuel filter is a cartridge type rather than the spin-on type used in the 2.8 model. So the complete assembly supposedly has to be removed so that the top of the assembly can be unscrewed to enable the element to be removed. But they also say the same for the 2.8 but it can be done as stated without removing the complete assembly from the firewall.
You will have to try it & see if the 3.0 can be done using the same method, unscrewing the base from the top while in place on the firewall making sure you don't crush or damage the casing. The rapid connector fuel line on the casing side will have to be disconnected along with the water sensor wiring connector to unscrew the bottom casing from the top half otherwise the complete filter assembly will have to be removed from the firewall (2 rapid connector fuel lines & two wiring connectors & slide complete assembly upwards) & done in the vice. There is also a bleed screw on the side of the lower casing. I would think if the lower casing is filled with new diesel to near the top & replaced as in the 2.8 you could use the same multiple ignition on method to bleed the air out of the lines.
Cheers

Hello FreeSpirit. I have a Peugeot Boxer, and I thank you for your fine instructions about changing the fuel filter. I believe what you say should work in my car. I loved the tips about refilling fuel into the new filter, and even more, the tips about gettíng rid of the air by operating the low pressure fuel pump. Thank you very much. Rony1xyz.

Re: How To Change A Fuel Filter On A 2.8jtd

2.0 has a spin on filter as far as I know easier still, I would really recommend people don't recycle the filter diesel in a common rail or unit injector engine for the sake of a few pence.

Re: How To Change A Fuel Filter On A 2.8jtd

Hi
When I wrote that guide it was the first time I had changed the filter & didn't have a container of fresh clean diesel handy at the time but as there does not seem to be a way for me to edit or add to any of my threads/posts once posted on the FF (unlike other forums), I cannot revise it. But I agree with "moodrater" I would change it to read - use fresh clean diesel to fill the new filter bearing in mind the very fine tolerances that are used in CRD injection systems.
Cheers
