Since my HPFP was upgraded this was a must to fully utilize the HPFP from spool. The install was not bad at all, pretty straight forward if you have the right tools. before I the fuel pump install I was running JB4 BEF on map 2 16psi, now I'm on jb4 mhd bef map6 e50 custom tune at 19psi. currently waiting on 3.5map sensor to tune over 20psi. I'll be posting races, WOT pulls. check my IG out for more frequent updates.

Thank you for putting together this video, any resource is useful when doing this yourself. Just an FYI for people looking to do this, the most difficult portion of this project occurs during the split scene at 7:51. The walbro 450 has a larger OD and longer length that do not work with this bucket. You will most likely destroy your bucket trying to make it fit properly . I essentially have a zip tie holding my pump in place. I assume the kits you buy online come with a custom plastic bucket that allow the pump to fit properly. It may be best to look into that as a better option.
Lmaoo precciate it bra 😂 you went thru all eht for us, now we know to put the. Clips in before starting da car. That’s real💯
Lmao I had to keep that in because it's all a learning experience
Thank you
I’m trying to upgrade my fuel pump into my N55 will I need to run E85 only or can I still run 91 ?
how is this compared to aem 340 lph is it fine on stock or need a tune ?!
Do the hoses just magically come off or the fits weren't snug enough they came off by just pulling out the pump assembly?
5:19 what is the length of the additional tube that you bought
Can't recall, if you buy a fuel pump kit it should come with one. The line I bought was longer then the one that came with the fuel pump , either one would've worked
How did you get your needles to sweep please?
When you have jb4 installed it does that
@@jonburnquist of course lol silly me. I've got bootmod3 so doubt i can do that on bm3.
Would this be a stage 2.5 pump. Also what if I got the walbor 535, would it be the same thing or different.
This is stg 2 pump, I would say 535 pump is stg 2.5. But yes it should be the same process, but take a look at @slowpeed RUclips channel he just installed the 535 pump and everything you need he linked in his description
jbo_435i okay cool thank you. He installed the 525 pump but I’m guessing it’s the same aswell
jbo_435i what do you recommend for a hpfp, I’ve heard some people put a b58 hpfp
What hose sizes do I order bro?
The shorter one
Hi there, great diy video you save a lot by doing it yourself rather than buying one assembled! Great job! I have a question what size additional line did you use length and od? Thank you
Thanks, the tube size is 3/8" x 9.4"
jbo_435i thank you very much! Great DIY!!! How does the car drive now on full e?
@@flyr5fc I'm currently tuned for e50, but it runs strong and smooth
jbo_435i hi, again very informative video, i did my upgrade over the weekend and i wanted to ask did you have any issues with the fuel gauge after install? Mine showed less than 1/4 tank before install and went to almost a 1/2 after the install which i found weird. Thank you
@@flyr5fc I didnt notice at first but now I'm starting to run out of gas when I'm at a 1/4 on the gauge, I'm going back in the fuel tank this week
Fuel it tool pretty nice easy 1 2 3! For 25$ say less!
I learned, my latest lpfp replacement video showed I got the tool lol had too
Thanks man good video and very help full I you have the opportunity to install and wire a port injection system for n55 335 435 will be really good and appreciated because is just one video in RUclips and is for n54 so I guess people will like to see it for n55 as well
Thanks for the feedback. I would but I went the upgraded hpfp route instead of port injection. But this install was much needed for the n55 community
Gilberto Diaz have you found any videos yet
Sebastian Quinonez no
Hungry for more power ?
Imagine, spending 1k+ on a lfpf, hpfp. But skipping out on the fuel it tool 🔧 over 40 bucks. C'mon bruh
Learn from my mistakes. There is always more then one way to get the job done
Facts! Maad respect, you tackled this on your own! Great job
