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, mine did
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 5 seconds.
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
Jeff Hayes: Thanks mate
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!
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.
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?
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: I've never changed a diesel Pump, nevaer needed too on this van
DA H: Thanks so much for posting this. Question: How often does the pump need to be replaced?
Bevoin1970: No this job is easy to do, so long as you work in clean conditions and you don't damage pipe connections and rubber 'O' rings when refitting Pipes to diesel filter. Also make sure you run the engine after completion to purge the fuel pipes of any air bubbles otherwise difficulty in starting your engine may be experienced.
Good Luck :-)
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: Thank you for a nice comment - Greetings to Canada from the UK :-)
Radojko Cekerevac: Very Interesting That Professional Sprinters Mechanic Won,t Help us The are all Busters from all around the World . So we have to learn from each other , Lets all Professional Busters Go Broke . I am Sprinter Onwer but I am also Intercontinental Professional Ex-Boxer . Box in Belgrad , Paris London Montreal and Toronto . Best Regrds and aprisiasion for Your Video from C A N A D A .
Bevoin1970: Thanks for commenting :-)
WAFFENSS69: THANKS FOR POSTING
Bevoin1970: It really isn't difficult to do, Good Luck!
Fredolin Cardino: This is helpful for me as a sprinter van owner who relied with dealers services for many years. I will try to do this on my own from now on!
Bevoin1970: My pleasure thank you . :-)
Jerry Materez: helped me when i changed on my 211cdi :-)
Bevoin1970: Im no mechanic, and certainly no expert. My general knowledge has been acquired over many years, but thats all it is, just a general knowledge.
Lots of people change their oil / filter every 10,000 miles - I NEVER use clean engine oil with a dirty used oil filter, NO WAY! whats the point for such a low cost or renewing. If you change your engine oil, then change the filter too. I used to change my air & diesel filter every 30,000 - My van goes for approx 20-30.000 miles in between oil changes.
