Default changing the fuel filter...

who's changed the fuel filter on their 2001 era legacy? I guess it would be the uhhh, I can never remember this, is it the be/bg body? In any case, i have 60k miles now and bought a subaru filter to replace the original. Any tips or tricks to know ahead of time? Fords need a special tool, some cars need the pump's fuse pulled and the engine turned a few times to relieve pressure. Some cars need a lot of surrounding items taken off to get to the filter. So any special things to know before I start? I haven't even looked for the filter on the car yet, Is it in the engine bay or under the vehicle like on some other makes and models?!?

On my BD, it's on the driver's side of the engine compartment, toward the firewall. All you need to replace it is a philips screwdriver and either a pair of needle-nose pliers to twist the line off or a pick or something similar to break the seal on the fuel line. Then unplug both fuel pumps. The connections are underneath the rear seat, one on either side (Smaller one's for the jet pump, you don't really need to unplug this one but I do anyway... Takes an extra two seconds.) Then start the car and let it idle until it dies. Replace the filter, tighten your clamps down well, and plug both fuel pumps back in. Turn the key to 'on' and let it set just a second to pressurize the fuel lines, then start er' on up and enjoy cleaner fuel!

I just left the car overnight to depressurize the fuel lines... I kept a rag over the lines while I worked the line off - not too much twisting etc. It helps if the lines are warm, so you could heat them up with a hairdryer, or just leave the car in the sun for an hour or so.

I'd never done one, and it only took me about 20mins to do, even with all my newbie-fretting.

2000-2004 is BE/BH. Our filter is near the left front strut tower - a little metal can with a few, ah, fuel lines attached.

I did this pretty recently. According to the FSM, you're supposed to unplug the fuel pump relay (under the dash (sucks)), then crank a few times, which I did. Then I just twisted the hoses off slowly. If they're stuck, like mine were, I'd reccomend putting a rag around them before going at it with pliers so you don't tear the hose.

After that it's just hose off, hose off, clip off, filter out, filter in, clip on, hose on, hose on.

Don't forget to plug that relay back in before you try to start it!

It looks like a black beer can with a couple metal hose barbs coming out the top.

I would not recommend using a hairdryer or anything else with open elements near gasoline... If you value your car and eyebrows, that is. Sorry guys, no making toast or hot plates under the hood either.

I know people that smoke when they're working on engines, including fuel system. IMHO, not the safest thing to do.

But to each his own...

I desperately need to change my fuel filter too… I tried to change mine during my motor-swap but could not get any of the fuel lines to break their seal. I tried twisting them with a padded pair of pliers but they wouldn’t budge and were beginning to booger up. Is there some trick to breaking the seal without damaging the line? Maybe I should focus a sealed work lamp over them to heat em up? I was thinking about some kind of spray but who knows what that would do to the rubber…

I find a cigarette lighter or blow torch works best to heat up the lines so they are easier to remove.

<disclaimer> that is a joke, please do not blow yourself up </disclaimer>

There are some great tools available for breaking seals on vacuum lines, fuel lines, water lines, etc. I know Snap-On makes one specifically for this, but you can get any type of pick and use it. Think of a huge needle, and the end is not super sharp... the have curved ones, 90 deg. ones, straight, angled, etc. I've found these work GREAT for breaking the seal on a fuel line.

Your other option, depending on the length of hose you're trying to get loose, is to CAREFULLY cut the soft line just past the nipple on the fuel filter. Then use a razor blade and cut along the length of the portion still on the filter nipple. As long as you have enough line, you can just discard that 1/4" to 1/2" and pull the other line in to work. Or, you can just replace the line. Fuel line is very cheap. Just take the length in to an auto parts store and tell them to match it up and cut you a little over that length, just to be safe.
