Jay Cee: For those that are having trouble with priming the air from the fuel system
after a fuel filter change (which i did), i thought i would share what i
did to bleed the fuel system, and it worked.
For starters, the O rings, i took the old ones to a place that sells every
type of seal you could imagine, and they did not have this size, - The O
rings have to come from a Mercedes Benz dealer as a spare part, they are
not a standard size O ring, and if you try to fit anything else other than
the Mercedes Benz ones, they will probably tear going in - SO USE MERCEDES
BENZ O RINGS!!!! - VERY IMPORTANT!!!
After you have the O rings from Mercedes Benz, make sure there is no dirt
where they seat, and put a smear of grease on them, like in this video, or
they will probably tear going in.
If you have any tears or cuts in the O rings, the system will draw in air,
and the engine will not start and/or run.
After the filter is fitted, remove the middle fuel line from the top of the
filter, (the one with the little clip holding it),
Get a small funnel that fits snug into the middle hole in the top of the
fuel filter, and fill it up with diesel (about 250ml should do it), then
loosen the bleed screw on the top of the filter until you see air bubbles
coming out of the sides of the screw (the diesel in the funnel is pushing
the air out of the filter, keep filling the funnel if you have to), when
the bubbles stop coming out, and all that comes out is diesel, tighten the
bleed screw back up, leave the funnel in the top - the funnel still should
have some diesel in it.
Ok, the filter is now bled.....
Then, get hold of a fat syringe that will hold about 100 to 200ml of
liquid, (i got mine from an auto spares shop) with an end on it that fits
snugly in the fuel line that has been removed from the fuel filter (the
middle one we took of earlier), fill the syringe full of diesel and make
sure there is no air in the syringe at all. Then stick in the fuel
line/hose that goes to the middle of the fuel filter (make sure its a snug
fit), and start pushing the syringe and push the diesel through the fuel
line, when i did it, a few bubbles came up through the funnel full of fuel,
i kept pumping the syringe and it moved in about 1/4 inch.
Now the fuel line is purged.
Remove the funnel, and make sure diesel is full to the very top of the
middle hole (MAKE SURE ITS FULL TO THE VERY TOP) then fit the middle fuel
line back on to the filter.
Then start the engine, dont touch the accelerator pedal, it should fire,
I hope this helps someone out, i had major trouble getting mine to start,
it just would not fire at all, when i tried this method, it started within
Jeff Hayes: If l may give a bit off advice that Mercedes told me change the water trap
filter for a non water trap one as it is a common fault for the to say you
have water in your fuel after taking my tank off to check it l was given
this tip and it worked a treet
sarah newman: Thanks sooooooo much for showing me the RIGHT way and not the Haynes way!
The book says start the van. dont worry its self priming!
Self priming my arse!
Jeff Hayes: Thanks mate
Madlookin: great video...a friend replaced my filter (prior to me watching this vid)
van has been running...but now won't start, blown down the fuel line and
can hear bubbles in the tank, do you think problem could be filter wasnt
purged properly...and what to do?
Madlookin: followed your video...filled the filter, even poured diesel back down the
fuel line...started first turn of the key!...something she hasn't done for
along time...so many thanks for the vid.
1nd1p0p: Another excellent video: thanks for sharing.
One question: are there different options for the filter? On my 2000 311,
there is no no water sensor on the bottom of the fuel filter (nor anywhere
to connect one). Most dealers I've checked out online assume the filter
has the sensor so don't offer an alternative.
Bevoin1970: Danke Eric :-)
Bevoin1970: @dumbell2312 Air bubbles in the fuel line are BAD !!! in normal working
situations, however if you have just changed the fuel filter, you cant
avoid getting air in the system. By filling the diesel filter up with
diesel, you enable the engine to fire up quicker after filter change, then
if you drive a few miles around the block, this will purge the pipes of any
remaining air in the system, and all will be back to normal. Good for you
for attempting this yourself. Thanks for watching :-)
Bevoin1970: Its an electric fuel pump on the newer Sprinters, what you have to be
careful of is not sucking in more air once your engine is up and running.
This is where you need to take care in refitting diesel fuel pipes back to
your new filter, so long as the pipe connections are good and tight, air
tight etc, once initial air is bled from the fuel system all should be ok.
Once running take her for a spin, cover a few miles to fully bleed the air
out the fuel lines.
Hesam0000: @Bevoin1970 The last time I went to a dealer for service was 15 years ago
for diagnosis and that was when no one else owned diag. equipment. Now in
America you can buy cheap diag. equipment, buy cheap parts online and have
some mechanic install them at a low, pre-set charge. I love to put the
sprinter engine plus 5-speed trans on a 1990-91 mercedes 350 SDL.
bassmandudge: @Bevoin1970 Leaving alone..but TBH the red light has never come on..even on
start up..I always thought it was just there as a warning light and it had
never been needed..lol..
Chipchoo: Hi Sprinter Lovers from Seattle, USA I have done filter change myself on
the V6, 2007 model. It is a little bit easier since it you don't have to
deal with the water drain plug at the bottom of the fuel filter. My comment
was: doesn't he need a special pair of pliers to take off those special
hose clams? and Doesn't he need to disconnect the battery terminal before
he change the filter? Just some thoughts!
Begbucks: @Bevoin1970 ^_^
Tom Seddon: this isnt easy for a new movano!
bbky77: Hay mate.my water lite not competing on at all and will only clutch
start.will not start with key.
dumbell2312: Excellent video! I recently changed the diesel filter on a renault kangoo
1.5dci, it was very straight forward, only thing I would be concerned with
is the air bubbles in the tube but its driving ok, Is it ok to have some
air bubbles in the system? or do you nedd to get rid of all of them?
bassmandudge: I set about a full service on my 04 sprinter following all your vids for
fuel air and oil service. Absolutely brilliant. Thanks you for uploading
these. One question though..the water sensor has never come on in my van
since i have owned it (5 years) the electrical connector plug on the loom
doesn't click into the sensor..it feels like there should be a retaining
catch on the left side but no matter what I do I can't get it to engage,
should it? of is it just a simple push fit? Thanks
Bevoin1970: @antpilk No I have never heard anything like that, saying that I have
changed this filter many many times and never had a problem in 300,000
Bevoin1970: Do you still see air bubbles in your fuel line? if yes & you have just
changed the diesel filter, you may have damaged one of the O rings. I have
had same situation. I had to replace the centre plastic pipe that goes into
the filter, it comes with a new O ring. It sounds to me like your sucking
air in from somewhere. Smear a small amount of grease around all the O
rings before assembly. I have never changed the water sensor O ring, bottom
of filter. No air can be allowed to get into fuel lines
Bevoin1970: I've never changed a diesel Pump, nevaer needed too on this van
Bevoin1970: My pleasure, if you managed to do what I did in this film, successfully,
and saved yourself a few £ or $ without much hassle, then I did my job
well. Good on you for having a go. :-)

jblp0wer: colegu :)
MAGERIA KAMAU: Thank you very much, we have been calling a mechanic and he pretend to be
so important to do just this, Now I do this first thing morning.
Bevoin1970: @Hesam0000 Thats a lot of oil changes... :-)
Bevoin1970: Thats ok, thanks and please keep me informed, Im very interested to find
out what the problem is. Good luck.
Bevoin1970: @kkhan42 Thank you - Hope you find them useful to you as a Sprinter owner.
Bevoin1970: @jellysidhu The more air you leave in the system, the more difficulty you
will have starting the engine up after a filter change. By filling the
filter with fuel, your making starting up easier, then continue to run the
engine to help bleed out remaining air in the pipes...
hdidane00: im real confused here i have a mitsubishi pajero and i have just been told
by my mecanic to change it at every oil change or 5000 miles now you are
saying 30k which is it. also oil filter he said every 2 oil changes or
6000k. pls help.
Bevoin1970: Aaah the dreaded injectors, not changed any myself, although I have heard
horror stories of them getting broken off and the head having to be drilled
Begbucks: @altevespa Just like "Covairwild" uses Thanks for the tip!
degsy49: I had problem with air in the pipes today. changed the middle fuel pipe and
everything was ok. Its a standard problem on mercs with not starting or
vehice running rough
Bevoin1970: @geisterbahn1 I reckon if you get a good Sprinter, you'll be fine. Anything
else that crops up is just down to chance really.
Bevoin1970: You must have air in your fuel lines, you need to get as much air out as
possible, and make sure you haven't damaged the 'O' rings on the pipes that
go into the fuel filter. It may take the engine quite a while of turning
over before it fires up again.
Bevoin1970: @altevespa Thanks for the tip - I'll look out for some on ebay. :-)
Bevoin1970: Sorry I cant help you, I have no idea.
noitatic5: I will take it to the shop and let them check for leaking injectors, will
keep you informed on what they find. Thanks again for all your help.
shay clarke: looks complicated!
Supatipanno J: I changed the fuel & air filter today with ease due to seeing your video,
however it (fuel) was more buried in the engine bay as the engine is the
2.7 litre 5 cylinder. I couldnt get the oil filter housing loosened using
the filter wrench for this model as it is a smaller diameter (75mm). Also
where is the cabin filter housed? I couldnt find it anywhere on my 2002
model to fit a fresh one
Bevoin1970: @HashiriyaSquadron Thanks for the comment, hope the Sprinter is ok now? I
know that feeling well of a sick Sprinter, not nice....
Bevoin1970: Thank you, Glad to be of some service. England says hello back !! :-)
jelly sidhu: its really helpful. thanks for uploading step by step. i m just wondring if
there is no need to get the ai out?
Bevoin1970: Im sure mine is an electrical pump, because if you listen very carefully
when turning the ignition on you get to hear it ever so slightly...
degsy49: good video, just like i do it at work at my hire van work
Alexander stiuca-seracu: i would have a question......i have a 2002 sprinter 2.7....i got it (2
owner) at 1750miles in 2012...the van sat or a long time.....now it has
13.500miles and i noticed that the light diesel filter turns on(and stays
on for 3-4 sec)when i turn the van on then shuts off....what should i do ?
i think it is too early to change the filter everything is new....could i
drain the water out ??? out of the drain ???would that help....thx
zack mcclain: @Bevoin1970 yea our untaxed diesel is red that diesel in the vid just
seemed to have an blue color to it lol is that like company fuel or
Bevoin1970: Just like to say Im an owner/ driver, with an engineering mind and an
aversion to paying hefty garage bills. I don't possess all the specialist
tools available to Mercedes Mechanics, just what's available around the
home, so yes there probably are special pliers for doing this, I just don't
have them. Also why disconnect the battery just to unplug a water drain
plug? It's not live and the ignition isn't switched on so nothing will
happen, Im just simply pulling the plug out. Thanx for watching
saycheese10times: Very informative and great presentation. 5 stars for you.
geisterbahn1: Im gonna buy a 02 or 03 plate 311 mwb for trips to paris and back once a
week any big problems with the 02 or 03 plates 311s thx nice job
