I changed my filter out at 57,275 miles. The total tune up is in work and recently the car has been slightly down on power. I've changed the plugs, oil and cleaned the maf and KN. Part throttle accel reveiled some flat spots and was becoming more pronounced. O2's are going in soon but i thought "what the hell" as i gave the fuel filter a change. WOW it made the difference! Never seen a fuel filter make that much of a difference. Musta been nasty in there. Still have to do the o2's and plug wires. No pcm scanner yet so i had to use a little old intuition . Anybody ever measured a pressure difference before and after a filter change? Probably doesnt take that much of a drop to start acting up like mine did.

Good to hear!
I am starting to notice a flat spot as well and fuel filter was the first thing I thought about...Looks like I'm going to have to do that today...

I always make sure all the little things are maintained such as the oil, air, and fuel filters. To me it saves me some time when something isn't right since I know it's nothing minor like a filter.

Glad to hear it's running better.

How often do you guys change your fuel filters? I changed mine out at 40k, and I'm coming around 60k now, it feels kinda like it's time...

I'm not sure if there is an actual consensus on how often to change your fuel filter....Some guys change every 10k others are more like 40k.......if it 'feels' like its time, its probably time.

next time you change it try hitting it on the side or tapping it with a little force and watch what comes out of it be sure to watch its ugly what comes out of a fuel filter honestly, black liquid stuff and i've always run 93 octane!

lunatik

the old filter is long gone or i would have tried tapping it on the side. i'll do that next time if i can remember. I think the filter company stated to change it every year. Thats sounds right for most of our DD's. That would put me right at every 10k.ish.

Any write ups on how to do this? Never have changed my own filter.

Change it every year or every 15-20k miles.

yea im with snake charmer on this it's my limit on fuel filter changing too, sometimes i go even sooner if i have been getting gas from alot of different stations you never know now with water in gas and god knows what else!

Guess i'll start getting a fuel filter with every 3-4th oil change then. Cheap insurance too concidering the pain of replacing a fuel pump + the $$.
Has anyone done a before and after replacing fuel filter psi check? My 70+mph punch came back alive after the filter change. Just curious as to how much pressure some of us wer actually losing. strictly guessing a couple of #'s?

Your acceleration flat spot...I've got a bad one at about 2500-2800rpm. will give this a try. Still need to do plugs and wires (ugh). I'm still intimidated on that right side cylinder bank.
