Question Replacing Fuel Filter

Hi all,

I have a '00 RS w/ 30Kmiles on it. I'm planning on replacing the plugs, air & fuel filters this weekend. I think the plugs and air filter should be relatively easy. My only concern is the fuel filter. Does anyone have any tips on changing it? Do you need to first pull the fuel pump fuse while the engine is running to minimize the amount of fuel in the lines/filter? Any pointers would be greatly appreciated.

Thanks,
Jeff

I'm sure there's an official method to do it, but I just did mine first thing in the morning, after it sat all night. Cold engine, no fuel pressure, no problem. Just took the lines loose, and put the new one in.

Good luck-
Rich

Pulling the fuse greatly helps to reduce fuel spillage.

I've always hated working on fuel lines in the engine compartment, as the heat tends to harden up the fuel hoses. They can be very difficult to remove from the fuel filter barbs, so be careful not damage the hoses. I had to cut one of mine off and replace the hose, since it was on so tight.

When you're ready to start the car up again, turn the key from Off to Ignition several times to help prime the fuel system, with a few seconds pause between each step. Mine took about 3 times before fuel pressure built up to 30+ psi. It's not entirely necessary, but it's better than waiting a second or more longer for the fuel lines fill back up again while cranking.

If you let the car sit overnight, there's no need to pull the fuse and run the car. There is very little pressure in the fuel lines, at that point.

It's very simple to do, just unclip it and remove/reconnect the hoses. The filter is still full of fuel, though, so watch that.

Plugs can actually be pretty tricky, just because of their location. Take a look and make sure you have the proper tools before you get started.

I just replaced my fuel filter and plugs too, I have 30K on MY00. Let me tell you the fuel filter is a breeze and these are good tips your getting.

Now the pain in the azz I thought was the plugs. I had to buy an extension because the plugs are so deep in the heads(no big deal rightbut thats not it.) It is pretty tight on the back plugs. I had to pull the wiper box out to get to the plug. You might want to look for some pointers on the plugs. I found them to be the real task.

It's pretty much standard proceedure to pull the washer fluid reservior out for the spark plug change. Two little screws and the pump plug, not really a huge task. On the MY99, you have to remove the top of the stock airbox and panel filter also.

Be prepared to spill a few drops of gas on the fuel filter change. The filter itself will be full of gas. Just have a rag handy and use the caps from the new filter to plug the old inlet tubes as you do it, one tube at a time. That should minimize the spillage. Fuel filter change takes about 15 minutes if that. Make sure the key is not in the ignition, or you have the fuse pulled. And don't smoke when you do it (DUH!)

Fred

PS- don't forget anti-sieze and dielectric grease for the new plugs.

Woa...I didn't realize the fuel filter was so easy to change. I always change my spark plugs and didn't think it was all that bad.

Cool

I didn't even know where the fuel filter was when I bought the replacement. When I saw where it was eeeeeeeeaaaaasy!

Spark plugs were a snap too, I was used to jacking up the car and going in through the wheel wells on my old Chevy's!

Pretty good info here!!!

I'll be doing my 30K work next week on my MY99 OBS. Couple of questions though, assuming you picked a Subaru fuel filter; how much was it and did you get it from the dealer or somewhere cheaper? Also, just where is the location of the fuel filter? I'm betting that there isn't much difference btw the 2.2L and the 2.5L location.

Thanks folks!!

imprezadan- pretty much all you need to remove is the washer fluid resevior. Though I haven't gotten around to changing the plugs yet (everyone around here is out of the NGKs

Check out www.azscooby.com and goto the mods section for the impreza. There are instructions as what needs to be done.

Hope this helps.

on the 2.5, the fuel filter is right next to the windshield washer fluid reservoir. it's a silver can-shaped thing, about 3 inches tall with 2 bent pieces sticking out the top.

Thanks Roger!!

I took a gander and there it is right in front of may face; it looks like easy would be an understatement. It's right where you pointed it out. Only thing was that it's a black canister.

Thanks again for the info, off to Pep Boys!!
