Thanks for making the video, I have a 09 fxt and it has the same design, wanted to be sure. I suggest using some axle grease or engine oil on the orings when assembling. I do fuel pump recalls at work, and sometimes the oring for the pump splits when cramming it together. You can't see it unfortunately, but eventually the pressure loss will cause issues. It happens every now and then, so we test drive them to double check.
I agree with a slight amount of engine oil on the o rings, or Vaseline, but not axle grease. Axle grease is thick & if it gets into the lines it will plug up injectors, FPR & other fuel components. Appreciate the comment 🙌🏼
YAY!! I made the 9th person to like the video! Good stuff brother. Keep on make vids. I’ll be watching, I’m heading down the same rabbit hole with my 2012 sti hatch.
Have watched a few video's and yiurs seemed to have been more realistic and time. Ive also bought the aem pump same as yours and was wondering how the black and red cable but looks like not going to need it 😁. Another simple job I'll be able to do after new disc's, pads, exhaust and suspension 😀
No I haven’t hard wired the fuel pump yet. From factory your fuel pump is duty cycled by the factory ecu. This means that the ecu will rapidly turn the fuel pump on/off to achieve the perfect amount of fuel delivered to the injectors based on what the engine is demanding from other sensor readings (throttle position, AFR, MAP, etc.) Hard wiring your fuel pump essentially changes your fuel pump to a constant 12v supply which makes it a 100% duty cycle. 100% duty cycle basically means the fuel pump is on all the time. Hard wiring your fuel pump is common for people to do in high horsepower cars so the injectors have a consistent delivery of fuel, then the injectors are duty cycled to inject the proper amount of fuel into the cylinders. At the power level I’m at (512whp & 440 torque) your don’t NEED to hardwire the pump. The factory ecu can handle duty cycling a 340lph pump & deliver enough fuel. Once you start getting into 450lph+ , or dual fuel pumps, I would highly advise hard wiring them to a constantly 12v supply with an inline relay to turn the pump on with ignition power. Very long reply but tried to give as much info as I could 👍🏼 hope that helps!
@@DanielKellert Agreed. ^ Unless you're pushing 450+WHP, I wouldn't do the iWire kit. Only really need to do the kit with a new hanger if you're pushing higher power, bigger pumps, bigger lines and injectors which is something you would be doing anyways for a higher HP goal.
Yup I did! I had no idea you were supposed to use 2 at the time so I learned the hard way 🤦🏻 I talk about it more in this video th-cam.com/video/NjwcQ9mm_5Q/w-d-xo.html
@@DanielKellert I had quick question. Did you have to remove the one that was inside the fuel pump housing? Where the fuel pump would sit? I know there is one in there but is that one you have to remove or leave in there?
@@jmadnesstv1167 When you take the pump out, the o ring might get stuck in the housing. If it does, take that o ring out of there & install the spacer & 2 new o rings on the AEM pump!
@@DanielKellert Bro actually i guess this model year (idk which other one) you just yank and pop the 3 separate points to separate the seat… Idk when it switched over but thats what i had to do if anyone is confused as well!
@@DanielKellert Yessir! Glad to see your content, been watching a few videos now for my fuel upgrades for my 08’ STi. Most of the YT videos are 15+ nowadays but this is my favorite body style.
For the 08-14 Sti you should double the o-rings on the housing to prevent a leak with the aem pump
I'm glad to see you man
Hope you still remember me ! high school was fuckn awesome dude
keep up with the videos bro !
Hell yeah I remember you man! Come back to Canada soon!! Thanks buddy 🤙🏼

Thanks for posting the vid! I will have to do this to my Sonata, and the design is very similar.
Super good video! You explain and show everything really well. (:
Thanks bud :)
make sure you put the second o ring on the came off the pump or you will have low fuel pressure
Super helpful video! I’m in the process of going fbo on my STi hatch, the adapter clip lowkey scared me. Thank you!
Ayyy atta boy 🤙🏼🤙🏼
Late to the game but thank you for the video! it helped a lot
Man I wanted to see it start thanks for the help tho 💪🏽

Thanks dude! Haha I’m lucky this video even made it to 9 likes 😂 good luck with your build!! Appreciate the support 🤙🏼
Loved it. Bout to replace mine on my ‘10 fxt
Good luck with the install! 👍🏼
Ia it possible to just purxhase and change out the whole assembly? Or does the fuel pump itself come separately?
Keep up the great vids I got an 08 sti that I'm about to install a new fuel system
Thank you! Means a lot!😃 Good luck with the install🤙🏼
Great video

I have a 2019 WRX premium and my pump assemble is different.
@Daniel Killert Did you ever install a hardwire kit? I see people saying they need to install one so the pump gets proper voltage.

Didn’t you forget the second o ring on top of the fuel pump?

Maybe release fuel pressure before and disconnect battery, clean surface before opening tank otherwise good Video
🙌🏼🙌🏼
Lol dude my rear seat does not have any clips to release to get my seat off, wtf? 2008 sti
It should! Just gotta use the eyes on the end of your fingers to find them 😅

@@piotrm6570 ahh I see it’s just a pop clip then! Glad you figured it out! Those are pretty common too!
