Def one of the best D.I.Y. channels on KZfaq 👌🏽👌🏽

Man this made such an insane difference in fuel pressure at high rpm for me. Thanks for video!

Finally a video showing how, thank you

Excellent work, love the videos!

gotta love those labored breathing sounds right in the mic

Damn bro thank you Frfr gonna save me a good 300 !

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?

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!

How is the fuel pump holding up? Have you ran full e85? What is Max fuel mixture you are running?

u the man 🔥🔥

I always come back for the 11:15

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!

Nice job! !

Great video

Did u have to make it bucketless to fit the sock or could you have left the bucket closed for a bucketed system ?

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?

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.

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.

Nice! Yes!!

Just did this running an e50 map on mhd a code pops up but everything runs fine. 👍

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?

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

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

Did the venturi become obsolete? Does it affect the pump's ability to pick up fuel at low tank?

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?

Should upload logs!

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.

Do you need a retune on MHD for the new pump?

Good stuff man I’m going to be doing my fuel pump next how we’ll have those zip ties hold up

I did stage 2 bucketless and keep getting 2A17 DMTL code even after changing DMTL any reasons why?

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

Nice video bro! Did you upgrade the whole line?

Thank you

Hi bro . I need some help . Where can I get this lpfp from other then fuel it ?

Hi, the pump at the affiliate link is out of stock... do you have another affiliate link to buy it? Thanks

Is there a direct kit that were able to use the new 525 pump

Getting a fuel pump error after doing this car seems to run fine still..

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?

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

Hey Man did you have any errors after the new pump was installed ?

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 , got a quick question for you , with this fuel pump and you’re running MHD E50 map , how much psi did you see ? Thanks !

Is this the same for n55 f30 cars

Did you have problems with the ekpm overheating?

Part numbers for the fittings?

This works w.out. cutting the bucket???

Is this work without cutting the bucket?

What size hose did he use for the pump

By any chance you have a new link for the fuel pump, the one you used isn’t working. Thanks for your help

Is the Venturi not needed in the new setup?

you can use radium 14-0547 for a simpler fuel pump adapter

Cam this be installed on a stock 2010 535xi?

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

what kind of hose do you use?

Did you put a fuel filter in it?

Just ordered the parts thank you

No Hobb’s switch ?

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

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!

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

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!

Could you show coding the EKPM to stop from having shadow faults for fuel pump plausibility codes?

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's the name of the song at 4:48 ?

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.

Could you of easily done a Walbro 525 fuel pump? And isn't going bucket less a bad idea for a track car?

Wow😮

Vehicular DIY can you only run up to e50 with this or can I run e83

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.

Works on N55?

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

hows your ekp holding up? any issues with overheating and shutoff due to the significant amperage draw increase?

what e85 mix can i do with this setup on mhd stage 2+??

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

Wow. Another great DIY.

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!

Did you have any problems with the EKP (fuel pump controller) overheating?

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.

For some reason my fuel pump 20a fuse keeps blowing after a few minutes of idling

What is the max e85 blend this can do?

Would this work on a N55 e92 335I ??

Why bother keeping the bucket if you just cut the bottom out and it's now non functioning?

do you have to cut the bottom of the bucket?

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 ?

My bucket broke into pieces...

Loud lifters?

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.

Ekp bypass...im tired of it

So with just this pump I can run 50% e85

fake walbro 450s are very common so look out for that

How’s this holding up for you?

heat gun on a fuel pump, clever idea.

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.
