If your car isn't starving for fuel you can assume it's good. You can also assume it's been on there since the car was built. You can also assume that it'll plug up sooner than later. Replace it. It's only a 15 minute job at the most.

Symptoms of a clogged fuel filter include sputtering at high RPM and difficulty starting. Ideally, you want to replace the filter before these problems occur... Subaru recommends replacing the fuel filter every 30k miles. It's a $20 part and is easily accessible in the engine bay. The toughest part of the install is getting the hoses off the filter, but a little patience goes a long way.
Here's another good how-to page. http://www.northursalia.com/m...r/ffilter.html |

I wish I had fancy schmancy tools for the job, it was more like...
Need nose pliers + elbow grease + strained fingers + cut on hand from when it slipped + 1 hour job + frustration at the lack of space on these damn boxer engines = fuel filter replacement. Next time I'm cutting those filthy hose lines and simply replacing them. quick hijack...can somebody explain to me how to replace the PCV valve? I can see the valve very clearly, I can disconnect the hose, I CANNOT get that BOV return hose out of the way. The clamp is facing downwards so I can't get that off, and there's not enough space to fit a wrench in there. Plus the BOV return hose is looking a bit worn, so I'll probably have to replace it, but if I can't get those clamps off, I can't replace jack. Any thoughts? |

....what are you talking about? iirc, the hoses simply were wiggled onto these hard lines. it looked fairly easy to simply cut them and install another pair. In any case...wrestling with extremely tough rubber lines were not my cup of tea, especially with very limited spacing.

I had no problems wiggling them off when I changed it. It took me all of 10 minutes to change out. This was on my old RS. I hear they moved the fuel filter next to the tank in the 05 wrx

Something to be wary of if you cut your fuel lines and need to replace them when you undertake this job is replacement of the hose. Most likely, the hose you are cutting is fuel injection hose which has a higher burst pressure, 30-35 psi, usually, and a higher price, usually about $8/ft. If you replace with the standard HVLP stuff that is about $1.99 per foot you stand to have that hose burst during service, a failure with predictable outcomes.

Damn, I wish it were that easy to change the fuel filter on the STis. Last time I checked, the fuel filter is attached to the fuel pump, permanently! So if you want to change the filter, you have to replace a perfectly working fuel pump along with it! It's a $500ish part!

Subaru moved the filter to the gas tank in 04 for the STi and all the other Subarus in 05 Seems like a major step backwards if you ask me.
However if you look at my page: http://www.scoobymods.com/forums/showthread.php?t=3645 It says you can get and replace only the filter (not sure what the PN is though) I'm not sure why people are saying you have to replace the fuel pump too. I do remember when the STi was new and somewhere in the US people got a rash of bad gas that clogged the filters, no one had the filters yet (or PN it was so new) that they had to change the whole assy that included the filter and pump. I'm just guessing here anyone know for sure? |

Funny in my link I have scans from the Service Manual showing the filter as a removable part. I wonder if they are doing the similar thing they did when our MAF's started going south in the 99's

Replacement interval for the in-tank filter is 60K, vs. 30K for the external filters.

Yep not saying it's cheaper, just that it doesn't have to be done as often.
