Remember this fact when changing the FP on a S55. No matter how low your fuel tank is prior to the install, the system is under pressure by design, so have a bucket ready because the pump will be sitting in a pool of gas when you pull it out
If you upgrade your HPFP first you reduce the Duty required on the lpfp... so that should be first upgrade.. then when you loose low pressure you upgrade that.
Everytime I go WOT passed 3k rpm. hpfp immediately drop to around 1200psi (targeted 2800ish). tried different maps including stock, results are same. new plugs and coils, any clue? thanks
2015 328i owner here. Drivetrain Malfunction error and Low Pressure Fuel Pump needs to be changed. The car is at 72,000 miles. I guess it is a common problem with F30's and you may need a new low pressure fuel pump anyway whether you need it for a upgrade or not
Sorry guys, you need an aftermarket EKP if you go stage 2.5. It crashes constantly after 5-10 minutes. PR and Fuel-It states that this isn't the case, however, everyone's results may vary. Had to order one from Evolution of Speed (BPM4) and no more issues. plug and play. Otherwise you are taking a change with your OEM, can replace and it may or may not overheat too.
As others have mentioned, there are dozens of issues related to upgrading the LPFP on the f30 platform due to overheating. Im running PS2 and xdi-35 HPFP on my 435i with no issues from the stock LPFP. Its simply not needed especially with the concern of overheating if you do upgrade the LPFP.
Agreed. I have seen a lot of 500+ hp N55 cars through Bimmerpost and forums etc. where none of them have upgraded the LPFP. Yes on the high pressure, but low pressure on these are fine for supplying up to 500 hp. Also, you will burn out the EKPM with an upgraded LPFP. Kies, you need to update this video with a little more info.
Are you also running the upgraded BMP4 LPFP control module? I’ve heard that the upgraded LPFP’s require more amperage, thus using more output from the fuel pump control module causing it to overheat and shut the car off. Way to avoid it is by using the Upgraded module
@@fredob1463 BS because i'm running the stage 2 PR Lpfp and my stock/factory EKPM3 over heats like crazy and shut my car off... I had to up grade to the BPM4.
Seen any issues with your EKPM module? Lots of reports of those burning up with additional current draw from a LPFP upgrade. Also, I have seen tons of datalogs now with no LPFP issues on 500hp plus cars. LPFP always steady, although the HPFP drops pressure. You must be running way more than 500 HP in this car?
I’ve read that you really don’t need a lpfp upgrade but it’s your hpfp you wanna upgrade, the stock lpfp can handle mixed up to e40 I’ve seen! But yes, it’s when upgrading the turbo that u will prob need a lpfp on the n55
Just installed my stage 2.5 from kies. Didn't listen about the full fuel tank. That was not fun and you should listen for sure. Must be below 3/4 or it'll do it for you.
What is your comment on a 2016 750ix with only 28k miles on it needing fuel pump replacement. At these low miles, it is surprising. Thought to get your opinion.
Okay I need some mechanical advice y'all. I upgraded my fuel injectors, to the Bosch EU6 injectors. I got a f30 328i. But I noticed a lag in power up top. So do I upgrade the low pressure? Or the high pressure fuel pump? Or both?
Hi, can you make a video on how to remove the whole fuel tank? as I have an issue with my left fuel gauge sensor and it needs to be fixed/changed. Thank you
Why does he only talk about the "F" series when the "E" platform is so very similar? In particular the E9X platform (Turbos ya know LOL). They could be including a whole huge segment of the BMW tuning world which is made up of so many series. I have both a E90 and an E46 M3 and I can understand why the E46 wouldn't be included but not the 135i's and 335i's of the "E" world. 2Cents.
Did you upgrade your EKPM3 LPFP control module? because I had to upgrade to the BPM4 by EOSPEED, due to my Stock/factory EKPM3 over heats and shut the car down because of my upgraded LPFP.
Quick question, I tuned my car and the fuel pump went bad. Is there a performance pump I need to get or just get regular pump? Car only has 40k miles. 2018 m550i
so if i'm at 450 whp... am i gunna eventually see degraded performance from my stock fuel system? you mention the stock system can do 400-450 whp and also that "you dont want to max it out" so I'm sort of inferring here. it seems to handle it fine now, but now youve got me wondering if that will change eventually (i'm done with power mods)
Good day Is there a fuel feed unit upgrade for a Bmw M140i. I recently had a problem that my fuel pump broke and was no longer delivering fuel to my engine...
Did you have to re-tune after changing from a factory > aftermarket LPFP? I would think not since the focus is within the injectors and HPFP but wondering what's going to happen once I slap in my Precision Stage 3 kit into my M4.
How did you reprogram the computer after replacing the fuel pump. I'm trying to replace my lpfp and was told by a bmw technician that the lpfp needs to be reprogrammed after it is replaced.
Brian, any issues with the increased current draw of the pump? I've read about a lot of issues where the stock wiring harness cant reliably handle the walbro 450 current draw. Se poeple seem to be ok and others are not
Will these pumps fit on the f10 535i n55 ? I know a log of parts are slightly different and I have bought parts that were supposed to fit both and they did not.
I'm a bit late on this, but am I able to install a fuel pump in the stock housing? Like if i didnt want to buy a drop in filter could i buy a walbro 450 and install it in the stock housing.
Hey brotha I had a quick question I’m currently full bolts on stage 2 on a e30 mix I’ve been on this setup for a while now and I’m trying to look for more power I would say any recommendations? Also if I wanna right a higher ethanol mix could I simply only upgrade the lpfp or should both pumps be upgraded before trying higher ethanol mixes. Thank you brotha
hello i have a question my fuel pump is broken against my bmw m140i i have changed various things donwpipe with a complete system other intake, charge pipes and a larger intercooler i drove with an mhd stage 2 and my pump has failed there is a possibility to upgrade a fuel pump for a b58?
Just installed my pr 2.5 lpfp got a warning light after shutting the car up that said "fuel pump" car runs and drives fine I was told the car cpu needs to adapt and it's just drawing more current and it'll go away after a little awhile anyone have any ideas is that normal
Wait so e85 makes less power than 93 I thought it was the other way around or is it just a bmw thing, don’t bully me lol I’m just trying to learn so I can do what’s best for my car to make the most amount of power

🤣
I'd love to know who needs Stage 3.5 because that's wild! Love these videos, able to learn a lot!
1stockf30 has 850whp on his 340i I’m guessing he has a stage 3.5😂

Can't wait for the video on doing the turbo right. I'm going to be following what you guys do and do it to my N55.

Does anyone know where to get that tool to take off that collar or if some other tool that’ll grip around the collar will work?
Great content! I know you folks are mostly F Series focused, is there an option for the E Series yall care to share? TIA
Where do I get that lock ring removal tool?
Ok great, but what about the EKP ?? Will it handle the stronger lpfp??
Hey Brian did you need a fuel pump control module to not overheat the stock one?
Does this apply to the 340i f30 as well
Yeah
Great video!!!
Thank you!
By any chance do you guys have a video on a LPFP install on a A90 supra?
do you have to recalibrate the fuel pump? asking bc the HPFP you have to
Okay I need some mechanical advice y'all.
I upgraded my fuel injectors, to the Bosch EU6 injectors.
I got a f30 328i.
But I noticed a lag in power up top.
So do I upgrade the low pressure?
Or the high pressure fuel pump?
Or both?
Does it hurt to upgrade those right away, before any mayjor upgrading happens or perhaps tuning?
Hi, can you make a video on how to remove the whole fuel tank?
as I have an issue with my left fuel gauge sensor and it needs to be fixed/changed.
Thank you
do you have any issues associated with the ekp module heating up and shutting fuel down with the updated lpfp?
Can it be available for 2020 Toyota Supra A90?
I'm sure supra lpfp almost as good as this one, and your hpfp as good as dorch st1 hpfp
🇧🇷🇧🇷🇧🇷👏🏻👏🏻, Awesome video, as usual !

Did you have any overheating on your Pkm module?
Do you recommend me to install on my fbo 335i n55 f30 even if I don’t have the hpfp? Don’t want issues
Did you upgrade your EKPM3 LPFP control module? because I
had to upgrade to the BPM4 by EOSPEED, due to my Stock/factory EKPM3 over heats and shut the car down because of my upgraded LPFP.
On f30 340i B58, LPFP isn't recommended till over 600whp correct?

I’m wondering the same thing
Have seen people add a low pressure fuel pump control module
Could this fit on my B58 ?? Thinking about buying
Why did my tuner not recommend this? I got stage1 dorch
Have a 2015 m4 is this the same and is the fuel sensor in the pump?
Will this work with an f30 340i, Haven't seen many LPFP solutions for the b58 as of yet. I think the only one I've seen comes from Vader solutions
i have a problem with the ekpm on my 328i F30 according to my carly scan. is it a common problem with the f30. are the modules interchangeable?
Don’t you get more horsepower when using e85 compared to 93?
Do I need this for a B58 engine if I’m only pushing 550whp?
So do u have to upgrade the hpfp on the m4 s55 engine? Or just good with the lpfp upgrade for around 600whp? Thanks
I can run just this on e85 with stock hpfp ?
Will these pumps fit on the f10 535i n55 ? I know a log of parts are slightly different and I have bought parts that were supposed to fit both and they did not.
I'm a bit late on this, but am I able to install a fuel pump in the stock housing? Like if i didnt want to buy a drop in filter could i buy a walbro 450 and install it in the stock housing.

Suck that you need to upgrade your fuel pump for miniscule 400hp.
