Bmw 335i N54 Ultimate HPFP Replacement Guide - High Pressure Fuel Pump

[@benreeves9761]

Hands down best video for HPFP replacement. Video was super clear and concise. This was a huge help.

[@tunerworld]

Thanks buddy! Means a lot :) I wanted to spend the extra time to make a clear video rather than just rushing it and skipping importsnr steps

[@kristopherbenko7194]

Removing the fuel fuse for this job is the best tip to know that also comes into play for any other mechanical fuel repairs or systems testing. Kudos! Thank you!

[@jeffmo7209]

Very informative. My n55 hpfp is starting to go out and I was thinking of going to a mechanic but now I'll be saving 400 bucks, thanks

[@Jeremy_E_Lynn]

Awesome video, made this job quite manageable and saved me a ton over the dealer.

[@Jeremy_E_Lynn]

Just finished the job on a 535i, left the intake in place which made it a little tight but still completely manageable. Could probably do it in 1 hour or so if it needs done again. Thank you again for this great video.

[@tunerworld]

Awesome man! Glad to hear :) how was getting to the lines with the intake manifold in place?

[@Jeremy_E_Lynn]

@@tunerworld Getting to the fuel lines wasn't bad once the sensor connector to the fuel pump was out of the way. The hardest part was getting the hex bolt closest to the block inserted when putting it back together. I ended up using one of those springy grabber claw things (sorry for the highly technical terms...lol) to hold the hex bolt by the head and went in from the back, into the guide hole, then used the long hex wrench to tighten it down with a 1/4 drive extension to tighten it per your video. Once I figured out to use that tool it went smoothly.

[@curtparham]

This was very helpful. I just replaced my HPFP and the car is running good again. Thanks

[@tunerworld]

Glad it helped :)

[@TheFrenchPug]

Where did you buy your pump from? How much?

[@huanweili7699]

Loved how you just tossed the parts into the engine bay after the fuel pump was installed. 😆 🤣 lol.

[@tunerworld]

Haha yep, that’s how I do all my repairs 😜

[@bmw135i7]

good guide i used this for my 2011 bmw 135i n55 didn't remove the intake and throttle body but would recommend doing so... low back is so sore trying to position body to fine that extra need angle.

[@tunerworld]

Awesome! Glad it helped :)

[@grantlong6586]

That trick is dope

[@tunerworld]

Allen wrench one? :)

[@maxon1672]

BEST hpfp guide on youtube. Do you have an instagram?

[@tunerworld]

Appreciate it man! Yep! @ChicagoN54

[@Xsocto18]

@@tunerworld is it same procedures for N55?

[@tunerworld]

@@Xsocto18 probably not exactly the same but I’m sure it’s similar. Never did it on an N55 before

[@joek4238]

Nice walkthrough. I'll be doing mine today.

[@tunerworld]

LMK how it goes

[@janbaglan7318]

Thanks Bro, now Im definitely getting an N54, this stuff ez

[@N54.S6]

Until you have to do turbos, oil pan, rear main seal, front main seal and every other N54 head ache that comes with it.

[@Syntax73]

HAHAHA Final reassembly was mad funny

[@tuneless7047]

It's an osias hpfp but it's more or less an ebay market replica sold under a million names. Could you touch on how it held up though? I'm at 115k miles already and it's time for a replacement but to be fair I don't need another 120k mile reliability. If my pump dies again and my car is still kicking, I could buy a second osias for half the price total of an oem. As long as this isn't a monthly repair, I think I could justify it just to get my car moving for now.

[@tunerworld]

Tuneless honestly the car always ran kind of weird. I assumed it was an OEM pump but the car runs much better with the used OEM pump I put in. If I were to suggest something, it would be to find a good used OEM pump for around $100 or less and run that!

[@tunerworld]

The car would always throw out a bunch of black smoke under full throttle. Always thought it was a tuning issue and the fact that it has downpipes and a PE mod on it, but who knows haha. I definitely wouldn’t run it again if I had the choice.

[@tunerworld]

Tuneless Let me know how it works for you if you do get it! And yeah honestly the job isn’t too bad either and it probably wouldn’t be a monthly repair so you should be fine

[@r3drogo]

the Osias HPFP is bad?

[@leefunkera]

Very helpful video! How do you check the pressure of the pump?

[@tunerworld]

leefunkera Thank you! You have to datalog the vehicle using MHD or JB4 or whatever software you prefer!

[@leefunkera]

HelpfulCarTips Gotcha! May I ask where you got your new pump? Also, do you recommend replacing the low pressure and/or high pressure fuel sensors?

[@tunerworld]

leefunkera I got mine used off a local N54 member!

[@tunerworld]

leefunkera You can replace the low pressure fuel sensor if you are having issues since you’re already in there. I know they have an updated part out for it! I didn’t however since I wasn’t having any issues with it

[@leefunkera]

HelpfulCarTips 👌your video saved me $500 that my goto shop wants for labor :)

[@codyd8683]

At 6:10 I really wish I thought about that removing the rear inlet…

[@tunerworld]

Now you know for next time :)

[@zachmartinez2442]

thank you for the video!! Helped a lot!!

[@tunerworld]

Glad it helped :) and anytime!!

[@onetransam1998]

I appreciate channels like yours that help us DIY amateurs save some cash on jobs that are NOT dealership requirement!! However, control the volume better, I had to turn it up around 2ish so i could unmistakenly hear you. But only to get my eardrums ruptured only10 seconds later from music that you switched to :( After a doctor visit and medication, I am fine now, and no hard feelings, just do not turn off your CC option

[@tunerworld]

Sorry about that, it was actually youtube who muted the video as some artist changed his music to Copyright. They had to edit the soundbite and in order to keep just my voice, it did that weird volume thing

[@benbernal7382]

Great vid

[@tunerworld]

Thank you! :)

[@maximebied1172]

hello great video! Do you have a model to advise me at a lower cost? I have mine to replace but I don't want to put anything in. Thank you in advance.

[@tunerworld]

A used OEM one would be my advice if you’re on a budget. If not, I would just go with a new one off FCP and get the lifetime warranty

[@emolliard]

Hi, Great video, doesn’t seems to be too difficult. I just have a question, I’ve a 2008 530i (n53 motor) and I need to replace the HPFP on it as well... do you know if it’s approximately the same position on the engine or not ? Thanks a lot for your answer

[@tunerworld]

Sorry I didn’t see this. Did you end up figuring it out?!

[@Acekid187]

What is the torque specs and sequence for the intake manifold

[@tunerworld]

11ft lbs from what I remember and I would start in the middle and tighten outwards for the sequence!

[@todotune2767]

Do the eBay hpfp work?

[@tunerworld]

I personally wouldn’t run one

[@TheeWilliamsFamilyy]

What HPFP to get for a 2007 335i

[@zeeetreee]

great video im actually looking for one for my 535xi you know anyone that has one for cheaper then retail i really dont wanna go with the ebay ones

[@tunerworld]

I wish I did! I usually go with used ones that are in decent condition

[@bmw135i7]

hi, which fuse do i remove if i have a 2011 bmw e82 135i for the hpfp, looking forward to your reply

[@tunerworld]

Hey, sorry I wouldn't know that off the top of my head but let me know if you figure it out!

[@anthonyjordan7847]

Legit video

[@tunerworld]

Thank you! :)

[@damon123jones]

No coding needed?

[@tunerworld]

Nope! No coding needed for the HPFP

[@SpeedCultureStudios]

Definitley sounds like an eBay fuel pump. Video made the job seem much less intimidating!

[@tunerworld]

Yah I’m sure it was haha. Thank you! We bought the car with a “new” HPFP but never really looked into it. If I were to do this job again without recording I’m confident I could have it done within an hour!

[@SpeedCultureStudios]

HelpfulCarTips great to know. Thanks again!

[@cruisecontrol4400]

My car smells of petrol, could it be to a chinese hpfp?

[@nove2987]

Hello! I was wondering if you could name the exact tools I would need to do this job? I’m not really experienced with working on cars too deeply but this is something I can do myself, can anyone name the tools for me? Thank you!

[@tunerworld]

Hey! If you look in the description of this video, you will see all of the tools I have used :)

[@JSneaks]

eBay

[@tunerworld]

That's what I was thinking

[@PartiBuoy]

So here's the real reason why the HPFP Fails. It's because GDI sucks. That's why. how could a part actually withstand such a pressure just to atomize the fuel? Idk how newer cars did it but my mazda 3 skyactiv engine has it figured out. Anyway's it's not just a lemon it's a failed concept. It tried too much. and the results was a failure.

[@PartiBuoy]

Car's are only getting worse.

[@gavinhare8668]

My 1series just came back from the garage from it stalling and not starting. When I came to pick it up on tow I noticed it had no coolant in the engine. Would this be taken out if they looked at the hpfp and is there anyway of them harming my drive chain as they said they think it’s jumped cause of a knockin noise it’s doin. It was never making a knockin noise when it got taken there by Rac

[@tunerworld]

gavin hare Usually coolant is not taken out when doing a HPFP, unless a line got busted along the process. Then again, I did this on a 3 series! As far as your other issues, I would start by having a reputable mechanic check your codes and see what’s wrong
