[@SHWELL11]

I just did this today,and thanks to this vid and Eddie's, I did it very confidently. TRY TO DO THIS MOD WITH A LOW TANK.. I had a full tank and made a huge mess.

[@JohnsonMotorsports]

Yeah it sucks if you don’t have an empty tank.

I’ll keep that in mind next time. At this point I don’t remember the details of the new plug.

[@warrenpecou7318]

Hey brother thanks on the video it help a lot...

[@JohnsonMotorsports]

Glad it helped!

[@Industrial_Mechanic]

Very good info. I just finished installing my fuel pump on my 2011 535i 6speed Manual. I am not sure if it is too big for my car since it is stock, but I've seen very good results on this pump. Let's see what happens. Thank you for the video. I used your video as reference. Good job.

[@JohnsonMotorsports]

Glad it helped! The only issue I have had to date, is I was doing multiple log pulls for the FMIC video I have coming soon. On around the 5th back to back log, I checked codes on the car and I had a ghost code for fuel pump power. I cleared the code and haven't seen it return.

[@Industrial_Mechanic]

@@JohnsonMotorsports Hi. I was wondering if you've had any problems with your fuel pump. My car just died again 5 blocks from my house. Assuming is the fuel pump. I am think I am going to get the one from FCP EURO. Any suggestions? Thank you. Be safe.

[@JohnsonMotorsports]

@@Industrial_Mechanic The only issue I have had, is I got a high voltage code from my EPK after doing multiple 0-100+ pulls for data logging. Do you have Ista??

[@Industrial_Mechanic]

@@JohnsonMotorsports Thank you for responding. I don't have Ista. Crazy thing is that after I paid a tow truck the car started the next day. I am am reading 700 psi at the rail on idle. The LPFP is running strong. I am very confused now. I would like to get a good diagnostic but I am afraid to drive it and getting stocked again. Towing is expensive for this car. lol. I was thinking on changing the high pressure fuel sensor to see what happens. Thanks again.

[@JohnsonMotorsports]

@@Industrial_Mechanic Yeah, changing the hpfp sensor has helped some people with this issue. If I were you, I would check into downloading Ista, to run the fuel pump diagnostic. It may shed some light on the issue. Worst case, you can replace the lpfp for around $150 or less and prepare the car for E. If you have to replace the hpfp it will get pricey. Recently, I have started having an issue were my fuel pressure shown on the hpfp is considerably low on start up. It only happens after the car is warmed up and it's very sporadic. Funny thing is it is immediately fixed but shutting off the car and immediately restarting. I am planning to replace my hpfp sensor as well.

[@qayyvm]

What is that plug purple and brown colour?

[@boosted6ers]

Late to the party here. Appreciate the tutorial. Methodical and well thought out presentation. Question Howd you splice the power and gnd w the oem parts?

[@JohnsonMotorsports]

I talked about that around 16:20 in the video. Basically cut the OEM wire and wired in the supplied Walbro connector.

[@kiingmccoy6383]

Hey man my car in normal mode mhd stage 2 is pulling back when i accelerate it loses power between 2000 to 4000 rpm and sometimes just 2000rpm do you think its the hpfp please help?

[@ebayram]

Very nice video. I didn't see the fuel level sensor attachment during the process and was wondering if the leveler is not attached to the pump assembly or the lid. I have this issue with my 2012 535i that right side fuel level sensor is kaput. From the "hidden" menu on the dash, the right side always reads the same resistance (50 ohms) no matter how full/empty the tank is. And the fuel level on the dash shows full once it is full but gets stuck at half tank and never moves below. I was planning to replace it with a new one from FCP Euro but kinda discouraged if its hidden somewhere hard to reach in the tank.

[@allindadoe03]

Were you able to figure out the fuel level sensor? I think I need to replace mine as well.

[@ebayram]

@@allindadoe03 So you have the same problem as mine? I am thinking to remove the "lid" on the tank and see if I can see/reach it and dare to replace with a new one. I watched another video where the dude replaced the whole tank only after discovering the sensor cable was unplugged somehow from the lid inside the tank.

[@paddoqclub]

Any problems with your EKPM fuel module. Lots of people running aftermarket LPFP have experienced melted fuel modules from too much voltage. Also how much e85 we’re you able to running without cold start problems and maintaining rail pressure at WOT? Thanks meng good channel.

[@JohnsonMotorsports]

The only issues I've had with the EKP has been when doing multiple back to back pulls. I got a shadow code of voltage. If you see in my DMTL Pump video, I decided to add some extra thermal pads to the EKP to help dissipate heat. Haven't had any issues recently.

[@antonio36o36]

Hey man how is the pump running? I have the same year car and was wondering if you've been able to find any upgraded hpfp for these cars?

[@JohnsonMotorsports]

The pump is running great now. No more issues. I haven’t done any research on the hpfp at this point.

[@DrewPrce]

Where did you get the new fuel hose ? tho one that went from the pump to the housing

[@JohnsonMotorsports]

The new fuel pump comes with a small hose to connect.

[@gilgonzalez5902]

Awesome video, i have a 2012 E70 with the N55 MHD stage 1 155k miles and it has a hesitation under hard acceleration. Ive been chasing it down for a year and cant figure it out, feels like a fuel issue. Ive replaced boost solenoid, vanos solenoids, HPFP (and sensor) and still have the hesitation. What do you think this could be? I wish i had codes or even shadow codes that would give me a hint!

[@dvk86]

I chased this same issue and it ended up being the LpFp he's replacing in this video. I didn't get any codes until it completely failed.

[@gilgonzalez5902]

@@dvk86 i ended up fixing the hesitation by pouring a few cans of BG 44K into the tank. My injectors were just super gunked up causing the hesitation, soon as the BG did its magic and cleaned them up the hesitation was gone and never came back.

Hi bro,i like your video and i would like to know,how about your car right after upgrade to lpfp?didnt come out any problems?because i am planning to install too to my car…😃and glad to see your updates more

[@JohnsonMotorsports]

No. No issues. The only issue I have had, was after doing multiple back to back pulls I got a code for increased power draw on the EPK module. If you see me DMTl/EPK video, I show how I add extra thermal padding to keep the EPK cooler.

[@tanpenghuang2921]

@@JohnsonMotorsports oh means after that no more issue ye?that great and tq for sharing your experience

[@cmyousef]

Hey Grant, did your new Walbro pump have a check valve? And if not did that cause any problems on start up or otherwise? Thanks!!

[@JohnsonMotorsports]

Man, it’s been a long time since my install. I know I haven’t had any issues with start up, but I don’t recall and check valve.

[@cmyousef]

@@JohnsonMotorsports Thanks, though! Great content!

[@Solowkey22]

Whats up man...soo this video is a couple years old, how has it held up? Have u had any issues? (I just bought this same lpfp and inside the box it says "vehicle should have the following upgrades prior to pump installation: Upgraded fuel pressure regulator, Larger fuel supply and return lines, 14 gauge or larger pump wiring, and Minimun 15 amp fuse) ....is the upgraded fuel preasure regulator and supply lines necessary? Im planning to just run the same regular gasoline in it.

[@JohnsonMotorsports]

It’s been great! Haven’t had any issues, except the random power draw issues if doing multiple pulls back to back. I add a EPK cooler a few months ago and everything is great. I haven’t done anything for upgraded fuel lines and such.

[@100marcusvinicius]

Hello. Do you have to upgrade you fuel pressure regular, or larger fuel supply or return lines?

[@JohnsonMotorsports]

No. You don't need to upgrade these lines unless you plan to run higher content of Ethanol. Usually around E50+.

[@tanpenghuang2921]

Bro i just purchase from summit racing,but the not supply the fuel line,so how ye?or where you bought it?

[@JohnsonMotorsports]

It's been a while, but I'm pretty sure my fuel pump kit came with a new fuel line. I don't recall purchasing one separately.

[@corrydurham4294]

What bmw app do you have installed on your phone? I saw you have gauges on your phone.

[@JohnsonMotorsports]

That’s the JB4 app.

[@Devil_Dog_Ultra]

On my e71 x6M I have 5 wires in the harness any advice ?

[@JohnsonMotorsports]

Have you checked on the forums? I would ask around regarding your model. I’m sure someone has done this before.

[@Devil_Dog_Ultra]

@@JohnsonMotorsports so i figured it all out through ista. Basically the car is not getting certain feedback from my walbro custom fuel pump. I can either tune the car or instal oem pump.

[@GSPMotorsports]

Did u ever have an issue with your idle studdering? I have a slight "missfire" that randomly happens when only at idle. It became more prominent once i did a mhd stage 2+ flash... Im thinking it could be the LPFP?

[@JohnsonMotorsports]

No, I still have a slight misfire on cold start. It’s not throwing a code anymore, but I can still feel it. I am going to pull the fuel injector to inspect.

[@rickross6368]

Seems to be more like HPFP actually

[@ArisFilms]

@@JohnsonMotorsports Did you ever end up resolving the cold-start hiccup?

[@JohnsonMotorsports]

@@ArisFilms Mine went away for awhile, but seems to be back now. I plan to swap out plugs soon and I hope that will help. I did plugs over a year ago and didn’t gap the plugs so I think that could be part of my issue.

[@dretookoo1364]

Did you experience it when you accelerate at high rpms, then the car suddenly drags?

[@JohnsonMotorsports]

Man, I’m not sure at high rpms. I was having issues as soon as the car was started. It was sporadic, but at startup I would get a really rough idle and would check fuel pressure on Jb4 logs.

[@wet_e92]

hey man when your car started bogging out, did you get any codes for the rail pressure sensor? i’m getting the same fuel pump codes but i’m also getting a rail pressure code

[@MgDesignBuild]

Hello Grant, Great job on your videos.I watched this one a while back, I installed the wallbro lpfp as well , and a Dorch hpfp as well. I have been running fine until yesterday I tuned to an E30 tune. Today my HPFP suddenly started making a noise , my car went into limp mode. I got the code 11AC02 High pressure fuel system. It could be that suddenly my lpfp is not delivering enough fuel to the hpfp. Did you rewire your high output lpfp to get more amps or voltage to it ? Your input would be much appreciated, Thank you, Mark in Denver Ps I have a 2013 535i with the N55 engine

[@JohnsonMotorsports]

Dang, unfortunately I don’t have any experience with the dorch hpfp. I have the early n55 with the N54 style hpfp. No, I didn’t rewire my setup either. I added thermal padding to my EPK and recently added the Terminator EPKS cooler kit. I’ve been running my Walbro 450 since October 2020 and typically an E50 blend. Everything has been good, but my recent log with my new F55 turbo is showing I may need to upgrade to the Walbro 525. We’ll see.

[@31juelz]

What was your symptoms with failing fuel pump

[@JohnsonMotorsports]

I don’t recall having symptoms. Car just wouldn’t restart at the gas pump.

[@legoman911]

How much can the stock fuel pump handle? I.e. can it handle a stage 2 tune with supporting mods?

[@JohnsonMotorsports]

Yes, typically a stock fuel pump can handle a stage 2 tune. I believe my fuel pump started to fail due to mileage and the introduction of E85. However, the new fuel pump allows me to increase my Ethanol blend.

@@twinscoupe Glad I could help. May want to look into the EKP mod as well, just to be safe. This fuel pump draws more power and you’ll get a code if you do too many back to back pulls.
