Thanks, Dave. Your photography is clear, good; your explanations were to the point. I'll be replacing my 2002 Forrester's regulator and that helped me. If I may, treat all the ground conneccions with a bit of anti-seize grease. I'll use a special hydraulic O ring grease for the little seals. Thanks again. 🕊
Man I love TH-cam and generous knowlegeable people such as yourself willing to make these videos! You have no idea how much this is going to help me, hopefully. I am struggling like most during the pandenmic and am forced to work on my own car, which I love working on cars but I know old muscle cars! Anyways, thank you!!!
You could tell the tone of his voice changed with "alright that was a bitch to get off." Lol you know that was one of those things you work on for way longer than you planned to. I'm watching this video because it's all I could find but I have an NA and this replacement is so much easier. Still very helpful to watch though, good video!
Ughhhh, you want to disconnect the NEGATIVE TERMINAL! ----NOT the Positive,,,, a circuit will look to complete itself by finding ground. When you eliminate the ground NEGATIVE terminal, you eliminate the possibility of the circuit completing itself.
Watching this video 8 years later. I’ve had a bank 1 too lean code pop up that has been irritating me. Watched this video and saw the vacuum like at 8:37. Ram downstairs to the garage and what do you know? Fuel pressure regulator vacuum hose broken.
Yes ...kind of. I read the ignition fuse also cuts power to the fuel pump. This is not true. There is no fuel pump fuse. To cut power to the fuel pump you need to remove the plastic kick panel on the passenger side foot well (one screw and a push pin) then disconnect the bright green plug. It's on the right side next to the door opening. It's a 4 pin plug. Remove the gas cap. Crank the motor a few times. Now the system is fully depressurized.
David, My car have hard start, need to crank a while then it will start but sloppy... the fuel pressure regulator might be the problem? recently I've change new bigger fuel pump and bigger injectors and tune. and the car having this problem now...please advise
Gravity297 my Subaru had the same problem when I bought it. It ended up being a loose wire at the main connector by the battery. Subaru only sells entire engine harness so I cut it in both ends and soilder it.
Hey just a question I'm lookin in to a fuel management issue have been getting low idle and dying occasionally accompanied by a howling sound that seems to be located where my regulator is, did you also have these symptoms? Going to replace my fuel filter this week as well lol just to be sure
Maybe air idle control valve? My '00 Outback would drop idle at stop signs and almost stall at red lights till I took it off and cleaned the piss out of it with break cleaner.
I am concerned I have this problem... misfire on 3 and 4... but it runs perfect on a full tank of gas. new fuel pump... new cat (which glowed red hot the other night when misfiring). I am about to pull the trigger on a new regulator. Anyone have experience with aftermarket regulators let me know
Bought my FPR off parts geek, seemed to be a reputable brand, installed part, but now its leaking??? New o ring and pump just doesnt make sense, if anyone can help, much appreciated
Omfg. I hope to god this is my problem. Car runs fine a lil noisy like a small vacuum leak (but I’ve replaced almost every rubber line and gasket. back fire a lot between 2000-3500 rpm when coasting in gear small studder at 3000-3500 rpm when partial throttle cruising down the road. Everything seems fine except that and HORRIBLE gas mileage. I’ve been replacing everything on this car if this doesn’t work i have wack compression because of the computer making the car rich making up for compression
@@jxx1234 actually yes I did! There’s no information on it ANYWHERE. I replace every sensor on the car and didn’t do shit. I upgraded my fuel pump to an aem. That help a lil with hesitation. Upgraded injectors and I scaled them and the tip enrichment. Still didn’t help. So LAST WEEK I finally went and bought an evap canister and replaced the T lines as well as the vacuum valve. KEEP THOSE DONT DELETE THEM. My mpg started going up! I get somewhere between 23-25 instead of 17!!!! I’ve had this car for 2 years and never got better than 17 highway!
@@jxx1234 if u have any questions HMU on insta @jus_me_ty I spent so much money on all these sensor I’d be happy to save people the trouble. Get a turbo blanket and heat shield it helps with heat soak and hesitation after driving a while. The evap help with mpg and my rpm is SOOOOO smooth now!

thanks for the video, the regulator is so well hidden in the bay I wasn't sure what I was getting myself into

@Dean Roy Definitely, been using Flixzone for since november myself :D
@Dean Roy Yea, I've been using flixzone for years myself =)
Did this fix the misfire problem?
Ughhhh, you want to disconnect the NEGATIVE TERMINAL! ----NOT the Positive,,,, a circuit will look to complete itself by finding ground. When you eliminate the ground NEGATIVE terminal, you eliminate the possibility of the circuit completing itself.
Disconnect the negative terminal so if you touch the wrench to the frame or body of the car, you will not create a huge spark.
Give this guy a drink of water for god sakes
Did it fix the missfire problem?
Just a tip don't use the WD-40 it will breakup the line and o-ring. Use other lube.
silicone lubricant spray works great for hoses and electrical connectors

...Didnt you mean to pull the fuel pump fuse, and not the ignition? The audible hiss indicates there was still fuel pressure in the lines.
Yes ...kind of. I read the ignition fuse also cuts power to the fuel pump. This is not true. There is no fuel pump fuse. To cut power to the fuel pump you need to remove the plastic kick panel on the passenger side foot well (one screw and a push pin) then disconnect the bright green plug.

David Mucci there is a fuel pump fuse under the hood (sbf no.5)
Did changing the FPR solve your misfires?
David, My car have hard start, need to crank a while then it will start but sloppy... the fuel pressure regulator might be the problem? recently I've change new bigger fuel pump and bigger injectors and tune. and the car having this problem now...please advise
Could be many things. I assume you mean a plug-in tune? Make sure the tune your uploading is for the injector, pump and FPR setup you have.
Very good video man! Kudos!!! You earned a like from me!
REGULATORRRS!.. mount up 🐕
Under load mine loses all power and Boggs down would this be a cause of that? Thanks in advance
Dawson Aucker did you find that problem? Mine does the same sometimes
Gravity297 my Subaru had the same problem when I bought it. It ended up being a loose wire at the main connector by the battery. Subaru only sells entire engine harness so I cut it in both ends and soilder it.
Gravity297 I just now seen this but I replaced fuel pump and pressure regulator and it fixed my problem
What OBD2are you using?? i have one for my WRX 2003 model and they don't seem to work!!
You mean OBD2 scanner? I use the ELM327 wifi scanner and the Dash Command app on my phone.
22670AA252
For the oem denso fuel regulator
Did it resolve your misfire?
Hi there
Do we need to retune for it? Thanks
This is replacement of the stock FPR. No retune is needed.

+Evan Hugh I had an odd howling every now and then also. I've read it could be the FPR swan song.
Maybe air idle control valve? My '00 Outback would drop idle at stop signs and almost stall at red lights till I took it off and cleaned the piss out of it with break cleaner.

you have a bad coil
nice vid.where did you get your regulator ?
+Mik3Rx8 Plug that part number into Amazon and it'll pop up.
could this part be burning out my fuel pump?
Probably not. A clogged fuel filter can burn it out. Or if you ran the car out of gas that can kill it too.
@Romeo Popaz I'm very curious of this myself.
@Romeo Popaz just bought my subaru and it's doing exactly what you stated
@Romeo Popaz did you figure yours out
