This video is part of a "Build Series" (see "Playlists" tab for all videos) for my 1998 Rally Blue Pearl RSTi Coupe (Impreza 2.5RS swapped with a EJ205 turbo engine), which is 1 of only 720 sold in the USDM for 1998. This RSTi Build has come a long way and includes a full archive of videos documenting how to: (1) Pull a EJ-series turbo engine, (2) Replace the head gaskets, (3) Add key upgrades to increase long-term reliability, and (4) Restore the interior to OEM specifications.

Another quick solution: I use 2 zip ties, slide them into the holding tags on both sides of the 90° positions and they lifted those tags up enough and the gas line slipped right off. Sweet! 😲

[@moparsrt1905]

Thanks for the tip. Here's one for you too. Beginning of video when you're talking about inlet and return fuel lines, you pointed to the black round diaphragm and called it the pressure regulator. That's actually just a damper to reduce vibration in the line. The regulator is on the RH side of the intake back side of the fuel rail.

[@SubaruONLY]

You are totally right on that one man. Thank you.

[@byloyuripka9624]

hey neighbor have you ever taken one apart? is it just a little nitrogen bladder? im curious if this piece failed what the characteristics would be. whether even altering running characteristics or just failure of fuel system pieces sooner?

[@harrisonmorin616]

I seriously don’t know why you don’t have more viewers. You’re amazing

[@djorkode1]

Cool trick! I ended breaking the clips on my wife's Subaru when I replaced the head gasket! Thanks for the detailed information...

[@SubaruONLY]

Thanks for taking a sec to say something. Much appreciated!!! Cheers!

[@joegarces8044]

I’m swapping out the engine on my 08 Outback. Your content has been much appreciated!

[@Huntershotit]

Luke you’re channel is awesome. Content is quality and I get to follow along as I build my subie too

[@SubaruONLY]

Thanks man!!! Try to make every one good!!

[@skmerti]

Just ran across your video today. Amazing presentation, to the point, you should make videos for living. It is pleasure to watch it. Thank you Sir!!! Also you are very organizes in your garage, all neatly placed and, that reflects your video production, thank you........

[@SubaruONLY]

Thanks a lot man. Feedback like this makes a difference! Cheers buddy! 👊

[@PotentialEn3rgy]

Very helpful, both the whiteboard and the tool modification

[@23hublock1]

Oh man, if only we had decent walk in tool shops here in the UK! Halfords here just doesn't quite cut it!

[@alzmanfield3659]

Man love your videos, very informative and detailed. Thanks alot..

[@joebush44]

Great video, except that’s not the fuel pressure regulator.

[@Hellman555]

pulsation dampener , not all models have them installed.

[@SubaruONLY]

Yep. Good catch man. Thanks for sharing for right info!! Cheers buddy!

[@URBANSTREETRAT]

Nice video and tip! This series is great for future reference. Thanks!

[@SubaruONLY]

Hell yea. You know it!! Thanks man!!

[@Mike_44]

Great mod to this tool! Thanks for this tutorial, very helpful!

[@user-dl3ll5cx1l]

In order to manage the pressure of the gas line, pull the fuse for the gas pump, then start the vehicle. Let the vehicle die and then you will have no pressure in the line.

[@DrewDiddy7703]

Nice tip, I’ve seen it done from the opposite end, this seems easier, is there Any need to pull a fuse or something to relieve fuel pressure first?

[@SubaruONLY]

Yes. Couple ways but most important is not to push fuel into the cylinders when no oil pressure present, that fuel washes down the lube on the cylinder walls and makes those rings start wearing the surface.

[@MriNfEk-ec9lg]

I just use zip ties. cut off the far edge flat and stick two into either side and the line slips out easy

[@SubaruONLY]

Yep - this works good! I’ve used many times too!

[@Joseph-uw8zz]

HELP! hopefully someone can help. I just recently got an 05 forester and did a head gasket job. I forgot to depressurize the fuel system so when I drive it around, it died on me. I read up on a forum and it said that there's no need to bleed the system. I was just wondering of this is true and if so, what could the problem be. I didn't have this issue before I started the job

[@johnonyango6069]

Hope the producers are seeing the challenges the Subaru guys are going through

[@jeff666p]

Could you use regular fuel injection hose to replace them?

[@DudesatRC]

Im looking for a cheap subaru, which do you recommend? Just for the winter to slide around with :). Thanks for your Channel!

[@SubaruONLY]

Hey - thank you!!! I go for a cheap impreza sedan or wagon. Easy to find cheap and all the awesome GC8 parts fit (and many newer model parts), so they’re easy to maintain on the cheap and upgrade over time.

[@codyfant2480]

Holy cow, thank you!

[@SubaruONLY]

Thank you!!! 👊

[@jorgelugo1411]

Awesome job man 🙏🙏🙏🙏

[@SubaruONLY]

Thanks!!! 👊👊👊

[@TStig39]

Where can I get one of those quick disconnect fittings?

[@1337theophany]

To anyone watching it’s a lot easier to just use hook picks to pull it

[@SubaruONLY]

Agree. That’s works great too. Cheers man!

[@1337theophany]

@@SubaruONLY can I say I really appreciate your videos using it to pull my Baja turbo to do the clutch

[@SubaruONLY]

Thanks buddy. I’ll keep making more every week! 👍

[@joez.9932]

This guy is Fucken great!! Very informative...new sub!!👍

[@SubaruONLY]

Love it! Just living the Subie life and sharing it with awesome fellow enthusiasts!!! Let’s keep this thing going strong!! 👊

[@paulb2948]

WARNING!! Easier Solution ==. Take a medium to large sized zip tie. cut both sides so its squared off. Then slide the cut ends under the "Tabs" in the clip, hold in place and pull the fitting off. Thank me later....

[@853rudedogs2]

Top stuff Luke

[@SubaruONLY]

Thank you! Cheers buddy - have a great week!!!

[@grice3000]

Great video 👍

[@SubaruONLY]

Thanks - much appreciated!

[@leandropim]

hi, i need to replace the fuel line hoses, i would like to know if it can be hold by clamps (not quick connector) or the hose will slip? thanks

[@SubaruONLY]

Hi. Yes, good high pressure fuel line hose clamp will work. You can replace all those quick connects if desired for sure.

[@JSTW8N]

@@SubaruONLY what size quick connects are they? Thanks

[@diegoordonez2677]

Awesome thank you for your knowledge

[@keken_25_pr48]

Hi man looking around here because i have 2007 2.5i impreza and have just 2 lines. Right now is bogging down after start driving and have about 55psi iddling and the return line have 0 psi.. ( No Codes )any suggest

[@SubaruONLY]

Maybe fuel blockage?

[@keken_25_pr48]

@@SubaruONLY it could be block but im not sure its this model use return line either.. keep researching and see

I was done by the 10th sucker, couldn’t finish it 😓😖

[@jonprophet1378]

Your video is detailed enough but come on, way to long.

[@killersmith92]

Ewwww autotragic WRX 😢 lol jk

[@SubaruONLY]

Hahah. So true! 👊 If I didn’t have three other manual Subarus, I’d never pick up an auto!! Plus, gonna JDM 6-speed swap it some day soon! *Random side note: Thinking that most turbo Subarus with an auto are less abused and they cost a couple grand less. So, maybe getting a better condition auto for coupe grand less and using that money to swap in JDM manual box will cost the same in the long run but get me far less abused car. Just a thought. Way more effort. But effort is free!!!

[@killersmith92]

@@SubaruONLY good thinking lol. Never thought of that
