- In this video I will show you how to upgrade your fuel pump on your N54 powered BMW on the cheap. I show you how to modify your stock fuel buckret and install a Walbro 450 LPH fuel pump capable of running E85. You basically make it bucketless.
I install this on my 2008 BMW 335i

Man this made such an insane difference in fuel pressure at high rpm for me. Thanks for video!
Still running fine?
Def one of the best D.I.Y. channels on RUclips 👌🏽👌🏽
Finally a video showing how, thank you
Excellent work, love the videos!
Damn bro thank you Frfr gonna save me a good 300 !
gotta love those labored breathing sounds right in the mic
u the man 🔥🔥
I would like to add to this diy that I followed it exactly with the same Gates rubber hose. The hose just failed on me. Couldn't handle the fuel and Texas heat. Going to replace with something better. Thanks!
Nice job! !
Thank you for the excellent video. Your videos are always so good and clear. But I am wondering what the advantage is of cutting the extra areas in the bucket at the bottom is and even what the advantage of a Bucketless system even is?
more flow
I always come back for the 11:15
How is the fuel pump holding up? Have you ran full e85? What is Max fuel mixture you are running?
Great video
I realize this post is a few years after the fact, but I want to say thank you anyway. After a lengthy list of repairs and upgrades (including new LP fuel sensor) I’ve just got my N54 135i, with its new Stage 1 VTT turbos, back on the road. No codes yet, but MHD is reporting a (shadow) inactive 2AAF. Datalogs show that the LPFP is generally working well at between 70-80 psi, but when I accelerate more aggressively it drops below 50 psi. Looks to me that the LPFP just can’t keep up with the new higher fuel demand. I’m a bit tight on cash at the moment so made the call to try out this project. Just bought all the gear and will get started on it soon!
i know Im asking randomly but does anybody know a tool to get back into an Instagram account..?
I stupidly lost the login password. I appreciate any tips you can offer me
@Luciano Harold instablaster =)
@Trey Evan i really appreciate your reply. I got to the site thru google and Im waiting for the hacking stuff atm.
I see it takes quite some time so I will reply here later with my results.
@Trey Evan It did the trick and I actually got access to my account again. Im so happy:D
Thanks so much, you saved my ass!
@Luciano Harold Happy to help :D
Make sure you line up the tab on the top part of the pump assembly before you tighten down the lock ring, unless you wanna be like me and shift the position of the tab 90 degrees and also have fuel pouring out the bottom of your car. I prolly should have paid more attention when the lock ring wasn't tightening properly, and I almost couldn't get it free again as it was spinning the whole assembly. Otherwise, pretty easy lol.
i had my friend install the lockring on the sending unit while i finished up my turbos, he ended up cracking the thing the tab goes in. couldent source the part so i ended up JB welding my sending unit shut...
Just in time for the project, however I'm 2021 we've discovered that the pump used is a fake walbro with the pinhole at the end where the filter goes. How's your pump holding up this far?
Just did this running an e50 map on mhd a code pops up but everything runs fine. 👍
Did u have to make it bucketless to fit the sock or could you have left the bucket closed for a bucketed system ?
Should upload logs!
Ordered your part list and following step by step. I would like know if cutting the factory bucket is necessary? I am not track or drag strip guy.
It's required to make it all fit yes.
Did the venturi become obsolete? Does it affect the pump's ability to pick up fuel at low tank?
is there any way to install the 450 walbro but keep the stock bucket style not turn it into a buckles style ?
If my logs have an erratic voltage reading on the lpf sensor (I have a brand new low pressure sensor) would that indicate a bad lpfp? It's a zigzag signal
Do you need a retune on MHD for the new pump?
Nice! Yes!!
I have a walbro 255 brand new from a car i didnt install it on. Do you think it would be worth it to buy a walbro 450 or another walbro 255 and run them in series?
Am in need of your help my 335xi is giving me so much trouble its misfiring like crazy cylinder 4 5 6,also its saying o2 sensor lines signal and mixture control 2.i change everything and am having the same problems it will not rev out
I did stage 2 bucketless and keep getting 2A17 DMTL code even after changing DMTL any reasons why?
Nice video bro! Did you upgrade the whole line?
don’t have to
Getting a fuel pump error after doing this car seems to run fine still..
Hi, the pump at the affiliate link is out of stock... do you have another affiliate link to buy it? Thanks
Hi bro . I need some help . Where can I get this lpfp from other then fuel it ?
Good stuff man I’m going to be doing my fuel pump next how we’ll have those zip ties hold up
No issues thus far.
Vehicular DIY Do you plan on doing a rewire kit in the future or is it pushing fuel just fine at the volts it’s at
Is there a direct kit that were able to use the new 525 pump
Hi can you remember what material the heat shrink is. I did this about 2 weeks back, pump was consistently pumping above 70 psi. Now at WOT its in the low 40's. Pulled the pump and saw the heat shrink has "unshrank". Got the 2A2D, plausibility code. Do you think the exposed wire could even cause this? BTW awesome channel
It’s DuPont 66 Nylon heat shrink
Thank you
Hey Man did you have any errors after the new pump was installed ?
Is this work without cutting the bucket?
This works w.out. cutting the bucket???
I have a full bolt on 535I with MHD. I want to do this upgrade but the stock OEM 535 fuel pump looks different than the stock OEM 335 pump. Do you think that Walbro unit will fit my 535 pump assembly?
as long as fitting is the same size
Great idea but I'd be worried that the zip ties and the heat shrink used on the wiring was not gasoline/e85 safe. If that degrades it will come loose and possibly cause a short in your tank.
Yeah if he didn't use nylon ties ' which come in fuel it kits' he's screwed.
@@luluhus1 They're made from DuPont 66 Nylon. The heat shrink says it's oil and fuel resistant. I'll dunk them in some E85 and check on them after a week to be safe.
@@VehicularDIY How was the test? :D
@@tskstar No news is good news i guess.. ¯\_(ツ)_/¯

Part numbers for the fittings?
Hey there, saw some of your videos and since you know quite a lot about direction injection bmw engines I kinda wanted to see your take on a problem that mine has been having for the past 3 and a half years ( ever since I bought it ) . So mine is an n43 ( pretty much an N53 with 4 cyl ) same high pressure fuel pump, same injectors, everything, so here's the issue, mine hesitates to start when it's warm, it doesn't do it constantly, it's doing it like 70% of the time, however, if I let it sit for hours or over night it starts up absolutely perfect. What I've been told it's that some of the injectors might be leaky, but shouldn't that cause some sort of missfire or cold start issues as well? I get good injectors values on ISTA, car has NEVER missfired in all these years, doesn't surge, doesn't hesitate, pulls and works like a charm once It starts. HPFP has no pressure issues as well. What's your take on it? The way it behaves is pretty much as if it struggles to ignite the gasoline in the cilinders from what I can hear. All sensors are ok, checked all the values and sensors, ISTA shows no fault, new starter, new timing chain and tensioner etc, new crankshaft rpm sensor, mpg is just fine, drives like a charm, I'm out of ideas and so is every single mechanic and the dealer. What's your take on it? It drives me insane. Oh and also, to describe the symptom, apart from the engine struggling to start, when it does it seems like it shakes it quite a bit, just like yours was doing on your N54 injectors DYI video when you said that when it's warm if you start it it shakes the engine pretty hard
Check your fuel pump module maybe or fuel filter regulator
Is this the same for n55 f30 cars
Did you put a fuel filter in it?
Did you have problems with the ekpm overheating?
What size hose did he use for the pump
what kind of hose do you use?
Wonderful video and explanation man! But there were some problems in the first start:
29F1 Fuel pressure, plausibility
29F2 Fuel High pressure System, fuel pressure
2B2C Fuel high pressure, plausibility, cold start
Sometimes half check engine light and sometimes both lights. Any help or advice?
Thank you!
Hey man how did you fix this? I'm planning get it done tmr. Thanks
This is a Low pressure pump , you are most likely having a High pressure fuel pump failure.
Common when running hard or E85
@@deviousJames29 yeah! In fact it was a hpfp failure, I changed and everything went ok!
@@carlosparra3719 That is Awesome ! How much did it cost you? Did you do it yourself? How long did it take you?
Is the Venturi not needed in the new setup?
Hey man did you have any fuel starvation or misfire issues with this setup? I’m really leaning towards doing this instead of spending $400+ on a bucketed setup but i’m afraid of fuel starvation issues. I usually don’t let the car get below a quarter tank. Is it as bad as people say?
Yes its bad bro
Especially with direct injection and expensive index 12 Injectors lol
No Hobb’s switch ?
Cam this be installed on a stock 2010 535xi?
By any chance you have a new link for the fuel pump, the one you used isn’t working. Thanks for your help
Hey sure try now.
Would this he good enough on the low pressure side to run full e85? Im thinking of doing this and getting the overdrive hpfp kit i really want to run full e85. Let me know thanks bro
Should be more than enough. These pumps support over 700whp without leaning on them on boosted LS builds.
Hey man , got a quick question for you , with this fuel pump and you’re running MHD E50 map , how much psi did you see ? Thanks !
It's around 18 psi boost. Fuel pressure will be in the low 70's dipping to low 60's
Works on N55?
Just ordered the parts thank you
Nathan Swisshelm how did it work out? Doing it myself tomorrow
@@chrismancuso6436 works great but damn it drinks fuel now
Also I only cut the front part of the bucket out so it doesn't slosh back and starve the pump but if you stay above 1/4 tank you should be fine.lmk if u got any questions
Nathan Swisshelm hey man, i did this yesterday, and I’m still having trouble getting the pump to fit with the y’all diy adapter he made. How did you position it to get it to fit back and hook up to all hoses? I’m stumped:/
Tall DIY Adapter**
Vehicular DIY can you only run up to e50 with this or can I run e83
Matt Crosby the pump can run up to e85
Love this! Really want to try it, but I am concerned about the zip ties submerged in e85. Any reason you didn't consider screwing it together or epoxy/jb weld. Maybe even use the same type of adhesive as the original it came with?
Thanks in advance!
Most versions of JB Weld + fuel = bad news.
I tested like all the jb welds on fuel they all failed after a few months max
Hey man I did this and I’m having a hard time getting the pump to fit back in place with the tall fitting, any advice? Thanks!
Have you tried trimming down the length of the hose a bit?
I’m trying that right now I noticed it was a bit long, just to make sure, the float and fuel line are facing the rear of the car right?
Could you of easily done a Walbro 525 fuel pump? And isn't going bucket less a bad idea for a track car?
Yes it's not a good idea to do that for the track. I'd leave the bucket as is then do the rest of the work.
@@in54ne82 Yep, let the sock filter bend inside why worry about hitting turns and having no power. But the venturi?
Curious on the Venturi myself
Do you need to do anything for the ekp module/wiring since this pump pulls more amps? Fuel it writes on their website it can overheat the ekp module
I think that is only for the stage 3 pump
Quick question, do you think this is perfectly fine to do without cutting into the bucket? I don’t want to run a bucketless pump due to my build being track build
Perhaps if you can obtain a smaller filter.
We're you able to not cut the bucket? I'm wondering why you can't just stuff the filter down in there even if it bends a bit?
@@VehicularDIY Hey man, what would you do with the venturi if i follow this exact process but keep my bucket?
Ismail Bayat you need to buy a Venturi Tee for your Fuel pump Filter to fit the Venturi.
hows your ekp holding up? any issues with overheating and shutoff due to the significant amperage draw increase?
No it's doing fine. I had put a little heat sink compound on it when I upgraded to a third generation module.
@@VehicularDIY interesting. mine (EKPM3, 335is, Fuel-it stage2 [walbro 450]) overheats after about 2-3 hours of highway driving, i get cylinder cutout code and limp mode...usually can just restart and keep driving but this last time i barely made it home.. im ordering a BPM4 from EOSpeed to replace it.
you can use radium 14-0547 for a simpler fuel pump adapter
So I think my HPFP is going. When I mash the throttle it goes into limp mode. Are there rebuilt HPFP’s you would recommend? It’s my sons 07 335i sedan. I have already put about 3k into it in the last year and until he gets a job I can’t keep dumping money into it. Are there cleaners you can use to degunk the HPFP? Any tips?
What codes did you get?
Luis using my generic code reader I had P142E and P3090.
I replaced the HPFP and the low pressure sensor just to be safe. She runs like a top now.
Is there any problem if I don't cut the bottom end of the bucket? I would like to get a "bucketed" style for the DIY upgrade.
Second this question
@@ryancrooks3645 i follow the instructions from a blog, whom make a DIY bucketed.
What's the name of the song at 4:48 ?
why was the bottom cut off the bucket? any reason ? im looking at pumps and thinking of doing similar but would prefer it to still have the bucket complete.
To make clearance for the sock and to help increase flow.
@@VehicularDIY do you think it would be possible to do it without cutting the bottom?
ive been tossing up with the walbro 450 and the walbro 525 (470) i have full boltons and hybrid turbos. currently getting fueling issues at wot lpfp dips to 35psi and the rail hpfp then dips to like 500.
Could you show coding the EKPM to stop from having shadow faults for fuel pump plausibility codes?
I'm going to yes. Going to program it via NCS Expert to code out the high current draw warnings.
Awesome I look fwd to it so when people ask about it on the fb groups I can just link your video vs having to explain it lol
Still waiting.... lolz
I ran into an issue with a high pressure fault code with this setup... Someone please let me know how to fix this issue...
what e85 mix can i do with this setup on mhd stage 2+??
About e40 safely
I’ve been following all your videos for quit some time. I wanted to ask you if coding or tuning is needed after installing walbro 450. I’m planning on doing this job in the next few days. I bought your exact same set up
Just tune and done ^ No coding required after install. Or ya know, spend an extra 50$ on one that's already together in bucket lol
@@N54.S6 mhd should be fine. Right?
@@luisGarcia-wl8bk correct.
@@N54.S6 thanks for the info. I greatly appreciate it
@@luisGarcia-wl8bk No problem buddy.
Hey hope you see this, what is the point of the sock sticking out, can you just shove it down in the bucket? Thank you.
I wondered the same. Another guy in the comments shared a link to a different sock on Amazon thats smaller
@@Harry_Ballsonya link?
Can you please tell me why do it need the two extension pieces ? It’s look like it may touch the top hat ? Can’t you just connect the hoses to the fuel pump directly? Thank you for the video!
Alan Tan did you end up doing this?
@@chrismancuso6436 does it work without extensions?
Fabien Naze I did it with the 2 fittings, face the outlet towards back of car
@@chrismancuso6436 ok thanks i'll do the same thing. everything works well for you?
Fabien Naze yea, works great I’m running e50 no problems
For some reason my fuel pump 20a fuse keeps blowing after a few minutes of idling
Best bet is to change it to a 25A fuse, see if that fixes it...
@@tedisboosted783 minimum required fuse for the pump is 30 Amps...
What is the max e85 blend this can do?
e60
full e85
Did you have any problems with the EKP (fuel pump controller) overheating?
Wow. Another great DIY.
Why bother keeping the bucket if you just cut the bottom out and it's now non functioning?
flinchey yeah just chuck all the components in loose and hope for the best 🤣
@@Uber-GT more, go a bucketless setup
Could have sold the complete factory pump and bucket for the equivalent of a billet bracket 🙄
Wow😮
Can I direct connect to Walboro pump without 90 degree fitting? Cause I did exactly the same and have a problem when drop the bucket back in tank, the top of buket is raise silghtly higher than sitting level. So, I can't put ring back on. No matter what I do, twist and move that 90 degree fitting around the top of bucket doesn't sit in its place properly
Would this work on a N55 e92 335I ??
Yes all the stage 2 pumps are the same regardless of N54 or N55.
Vehicular DIY thanks for the quick response :)
Loud lifters?
No. That’s the direct injection system. It’s normal. These injectors are just loud on cold starts.
N it’s not a push rod engine if I’m not mistaken
do you have to cut the bottom of the bucket?
For the pump to be able to take in enough fuel under load you do yes.
Vehicular DIY 👌🏽 thx bro
Are you planning on upgrading your turbos? That would be the only reason why I can think you would want to given I think you have stock turbos ?
Matthew Weisdorfer or wants to run a lot of ethanol content which is exactly the reason he gave at the beginning of the vid
So with just this pump I can run 50% e85
I don’t have to have injectors
@@mihaelstevic1027 yes even full e85 but you need port injection because hpfp can't keep up.
@@BimmerM5e39 what if you also upgraded the hpfp would it be sweet then for e85?
@@ashleys7416 Which upgrade do you know of?
BimmerM5e39 the VTTO double Barrel HPFP
My bucket broke into pieces...
Ekp bypass...im tired of it
Great video. I ain’t trying to do all that. I will spend the extra few hundred. Lol I drive a bmw not some Honda. Haha. I have the means.
fake walbro 450s are very common so look out for that
Are the fake ones any good?
@@Gendo3s2k theyre hit and miss. theres no quality assurance like with walbro.
How’s this holding up for you?
Still working. Making around 550 whp and holding a minimum of 56 psi. Mostly around 70psi
Vehicular DIY awesome. I’m running e25 on my stock LPF and it’s cutting injection at 6,000 rpm. Dropping below 40psi. Thinking this will be perfect. Can’t run over E50 with the stock HPFP correct?
Yeah only a super healthy one can run e60 so e50 is a safe bet. Make sure rail pressure isn't dropping on the high side after.
Vehicular DIY cool. Thanks for the reply.

This pump. The one you linked is out of stock.
heat gun on a fuel pump, clever idea.
Have a look again mate, he said make sure its extra dry and clear of fuel lol pay more attention next time.
this DIY wasn't very well thought out, the idea is there but if somebody watches this and pulls the pump directly from the fuel tank then proceeds to use a heat gun or soldering iron they are either going to end up with burns or a melted fuel pump.
did you miss the part where he said make sure its extra dry and clear of fuel? maybe buy a second one so its clear? or even that his has been sitting for months? lol. id say he thought about that as well so im not sure what youre going on about
1) If someone is watching this video, let's assume they're not idiots and know better
2) If all else fails...natural selection is an amazing thing that society needs to stop trying to prevent
Hey Ben, it sure would be cool if you'd revisit your very well thought-out criticism of this video!
