Thanks for posting this Omar... really appreciate it... you don't even want to know how much a garage said it would cost to do this job. I'm having to do the timing chain and phasers at the same time I'm doing this.... seriously rethinking my choice on a Mercedes...
I fixed mine 3 x after finally buying original Mercedes pump from European company with lifetime warranty!!! Better than 1y from MB Dealarship… Replaced 2weeks ago working great !! I can fix the pump in 3x less time than the first time now lol. Removed oil filter and air intake box that make the job much easier👌 Update today March 2024 still works great !
Well,when I purchased the car from this guy Mark first ride from the bank the engine light cane on !! He came with his buddy mechanic who erased the engine light while I was in bank getting money for the car. Basically when I stepped on gas ⛽️ the turbo engaged and it set the engine light and put car in limp mode ( lazy mode slow driving to prevent more damage) took it to MB they wanted around $2000 to fix it $209 diagnostic which I figured out on my own for free with my OBD reader or you can go some car parts shop they check engine light for free. The second faulty fuel pump I got from amazon was even worse my car just died on first intersection, luckily started up again so I turned around removed it again put my original bad one in and ordered from FCP they give you LIFE TIME WARRANTY not like MB dealership only 1-3 years if any and if you just buy a part from MB and put it in yourself there is no warranty. Once you do it several times it’s easy . Get a telescope mirror it helps because you can’t see at the back of the engine there are screws and the magnet which is inside of the fuel pump which have to line up to adjust it correctly to fit.
Just so everyone knows if you have less than 120k miles and it's under 10 years old you qualify for the free extended warranty repair on the High Pressure Fuel Pump.
@Paul Boerst me to brother it's good to have more info. No pun intended my friend. The job is tuff thoe I actually don't want another one nor from VW or audi.
Lol you took out the engine mounts and intake manifold. I don't do any of that. I can have the HPFP out in 10 minutes flat . No need for intake removal or engine mount removal. But sure as hell would do it on a customers car, to charge more hours, and add in a carbon cleaning of the valves and replacement of the pcv valve and maybe even the oil filter housing if it's leaking. Cause i done all that. BTW for anybody doing this job, Turn the crank to 52 , it will say that number on the crank pulley. Then the new pump will go in easy. ( make sure the new pump has the same rotation angle as the old pump that you took out, and then it will go in like butter.
Hi sranjesuper. Thanks for watching this video. Glad to read that it has a better easier way to replace as of for me this was the very first HPFP replacement. Thanks for the advise will do better when next HPFP problem comes around. As always like subscribe and God Bless You
@@omarlopez-eb2nd Yeah the hardest part is the 2 lines. With the air filter box out, there is enough space to crack open the 19mm with a wrench. The threads are very nice and fast, so all you have to do is crack it open. The low pressure is a bit hard to undo the 1 time clamp. Use a pick or screwdriver , and then just slide it off with a screwdriver or trim removal tool. If you got these 2 off, then you can do the rest very easily, because the intake manifold is not in the way of any of the bolts for the hpfp. Just make sure to set the Crankshaft pulley to 52 and it will be all easy. God Bless
Aloha snanjesuper 🤙🏽 did you release the HPFP as on this video at 3:35 ? Or you can just simply do so at the fuel pump when unscrewing the bolt ? Also do you know the tools needed for this job? The 2 fuel pump screws size and type ? I just talk to Mercedes they charging me $1700 for this job ... fuel pump for $760 I just ordered mine for $312 bright new ... it’s seems easy the way you described just worried about the crankshaft turn on 52 not sure how and the high pressure release.. it’s fuel so don’t want to make mess if I take off the hose and gas starts to gashing out on the engine 💣🤷🏽♂️ but I guess if i clamp the gas hose shouldn’t happen 😅than after the job is done do I have to measure the pressure in the HPFP? I know there is a tool box for that , in Orayley they offered me to buy that but they didn’t have the fuel pump...
@@worldfitnesstrainerradekve9234 No need to release pressure, i just unhooked the low pressure hose and some fuel came out. I put a rag under it to catch it. Not much fuel comes out. Maybe 15ml Obviously make sure your key is not in the car and make sure you give it some time to cool off. If the hose is pressurized, it will be maximum 80PSI but without pressure, it should be a couple of PSI The 52 mark is very easy to see on the crank pulley and there is a notch on the engine that you lign up the 52 with., I don't remember the exact sizes. I think i used 8mm flexible wrench for the 3 screws on the hpfp, a 19mm wrench for the big pressure hose, screwdrivers for the small pressure hose to break the metal clamp, and then use a new screwable clamp after. and there is a small bracket with a couple of bolts that holds the hpfp connector also 8mm. Overall, it takes me about 10 minutes to have the hpfp in my hand after 2 tries.
Hey man, how did you remove the manifold bolt all the way in the back? The one near the bracket that connects the block and the hpfp. It's blocked by the oil filter housing.
My friend i took the whole engine mounts apart too have some space. Little did i leran i dint have too do so much. According to the comments I've been receiving. But don't panic or get irritated. It's possible just have too wiggle the way out of there. And i believe i removed the oil housing aswell. Not too sure i dont remember. But know this, if anything is preventing you to get to where you want,,, if its removable then do it so..
Hi Pertti Largekrantz. Thanks for watching my video, hope you enjoyed it. Nice too know that you can replace hpfp without the hassle. I will try to replace when next Mercedes comes in. Thanks for your comment, it's never too late too try. God bless you. Like subscribe.
thanks bro ive been puttin off changing my oil filter housing gaskets might get it done soon after seeing this. Any tips on removing the starter ot should just leave in place
Omar that you for you post and with 8000 views you know its a issue . I do have one question and I'm sure other are wondering the same thing did you have to turn the crank to install ?
Hi Jay Swiatek. Thanks for watching this video. Apparently some guy told me you have to turn the crank shaft to 52. That way the you wont have any trouble installing the new HPFP. I dint turn anything, i dis it the hard way lol. But do turn the CS to 52 and try it that way. Hopefully it is that simple. As always God Bless you like subscribe and good luck
@@jaimemarun2841 well there is no kit to repair here in the valley texas. Amd it is best to replace with new hpfp, unless you want to pay again for a refurbished one that will most likely break again sooner than later.
@@mr.revling227 just remove the oil filter for more space. It's only 2 screws that holds the pump. Remove the hose clamp to the fuel line and replace with a regular hose clamp when installing the new one. The other fuel line is just a size 14 or 17 wrench I think. Remove oil filter, remove fuel lines on the bottom then the two torx screws that holds the pump. It's that simple.
@@calderondean bro you don’t have a RUclips lol? I need to change my fuel pump but I don’t want to go through all the hassle of taking all that stuff apart. And I’m definitely not trying to pay $2000 to have a shop do it. I need to see how it’s done so I can replicate the process.
@@unclemar8352sorry i should of made a video. Just remove the oil filter for more space. Buy a mini rachet set that has the small torx bits in the kit (Amazon). That's what you will use to remove the pumps torx screws. Cut off fuel clamp and replace it with a regular screw type clamp. Remove metal fuel line with a wrench. Pump should come out with no problem. It will be a little tight but not that hard.
@@calderondean thank you for the tips. I’m going to grab the new part and try it out. I’ll probably make a video on it just so more people can see that they don’t have to remove unnecessary parts to do this fix.
Hi Omar, I need to replace mine too and I saw in your video you used a spring hose clamp for the low pressure fuel line. Is that hose clamp enough to hold the pressure without leaking? And if it is where you get it? Thanks in advance
Yes sir they are replaceable. You can find them at any auto parts. Just make sure you don't leave it to loose, make sure it is nice and tight 🙄 i konw i know. That's what she said 🤣.
What a pitty you did this video missing the most interesting parts in fixing this common problem of Mercedes C class especially . The most interesting part is how you remove everything and how you install it back not forgetting to rotate the crankshaft to the 52°mark .
Hi Tyler Eaton, thanks for watching this video. I took it off for better reach. According to a fellow youtuber. He didn't have to remove it.. Not sure if it was true. But the way i did the job being it my first time, it took me a while but i good it done. Hope i answered your question. As always God Bless you and goodluck to you. Like subscribe
Hey bro I’m trying to same thing with my car but I can’t seem to get the spindle on the hpfp to line up with the engine. Any tips on that? I cant lift the engine out neither
What my co-worker and i did was, remove the hinge were you hook up a crane too lift the engine up. The one next too hpfp, also theres a vacuum line thats on the firewall next too brake booster then insert the hpfp a d twist the whole hpfp. You will have too remove the engine mounts lower the engine all the way down and it gives you great clearance too twist the spindle. Good luck its a job brother but patience is key
omar lopez I needed up taking off the heat shield right behind the engine and removed what I’m guessing is the heater core core coolant hose and that was 100 times easier then dropping the engine :) thanks hope this comment helps anyone else
turn the crank. think the bolt was a 27mm socket and extension. you need to watch the back of the cam and compare the degree of the key way of the high pressure fuel pump.
I don't think so brother. I really dint check that out brother. But its always best to replace it. A bit more costly but its effective. Good luck God Bless you
Hi Alfred Chavez, i currently dont have a shop anymore. But im in the RGV. Thanks for watching my video. Some say i over did this job. It was my first hpfp job. You can actually remove and replace hpfp without all the hassle. Like subscribe if you like good luck.
@@elatab11 oh wow yeah thats pretty far away. But there is more videos out there that show you how to do it yourself without doing all thay i did. I dismantled all do to it being a clients car. Hope you get it done brother good luck as always God Bless you like subscribe
I would but car has not returned to shop. Good thing. Im sorry it's not as of help too you brother. But i do explain how to fix and maneuver the parts. Sorry once again
It's useful enough to someone who sees a battery and a lot of stuff on the right side of the engine and are not clear where to start or were you will end up if you start. If you do not have a shop manual with step by step you have to write a shop procedure while you disassemble things and take pictures before removals in a complex procedure like this. The engine partial removal would be where I write the check to the Bosch shop and let them do it. I hate when there are parts left over after assembly, or the care won't start.
