I fabricate my own fuel pressure regulator lines based on IAPerformance and Cobb’s version for the notorious 08+ STI fuel stumble. This mod requires a tune, (not OTS map) to run correctly. This video is just a guide. Mod at your own risk!!

FPR (22670AA351) = $80 (amazon)
Doorman 800-080 5/16-5/16 x 2 = $15 (amazon)
Gates Barricade HP Injector Hose 3f = $15 (o'reilly)
Flex Sleeve 1/2" = $10 (radio shack)
Single ear clamps =10 (HF)
Total -> $130 (or $145 if you have to buy the tool)
Its worth doing it yourself.
Hey Joe
I was thinking of doing this mod because of the stumble at 3000 rpms. Has it helped? And do you need a tune to run this kit?
Why would you not put the crimp portion of the clamp on the bottom side, instead of on top for a cleaner look? You went to the trouble of using a sleeve and shrink tubing for a nice look!
hey man, would these quick disconnects work with a -6 an hose?
Question Joe. I have the IAP kit and was wondering what a dampener does? Do I need it?
just wondering why you put a dampner on the feed line seeing as how cobb dosent put one on theirs, they only put it on the return line
+octurbojoe lol at your commentary. it's pretty damn funny. I built this today, super simple, my only information I didn't gather was the routing of the relocated vac line. thanks for doing this video!
i got my IAP kit yesterday. i was informed that all we would need is the FPR from a 2004 sti. we looked up the part and its the same FPR on the IAP kit. i paid $130 for the kit so i dont feel as bad but its info i wish i knew prior to purchase
Hi there, could you please add the information of the exact damper and size of fittings that you used? Can't find that damper.
Which dealer? Which one do you suggest I need the fuel pressure regulator.. Which kind? Maybe eBay? But idk which one
Where do I get all these pieces??? Do you have the part number
Could you put the material list in your comment as well as the lengths for the lines? You've got me interested in this when I tune my car next month, would love to do this delete. Thanks OCTurboJoe, you showed a great tuner DYI for sure right here.
Are you selling these or what? ^_^
