Hopefully this will help someone else. This past Sunday, before the football game, I decided to check/replace the fuel filter on my car. When I purchased the car, it had around 45K miles on the odometer and it probably had never been changed since the car was new. I jacked up the rear and placed jackstands under the car for safety. I then slid my 38 year-old frame under the left side (sucking in my gut to do so) and looked at the filter. It looked like it had never been replaced and was all corroded up. I then hopped into my trusty pickup and went to purchase a new filter at Advance Auto. Total cost $6.00 and some change. Installed it and my car now pulls stronger in every gear.

I have changed a lot of these filters over the years but I have never had one make this big of a difference. It pulled good before but now it does it even better. Keep those filters changed guys.

Some people do it as often as once a year or 10000 mi for best performance but every two years should be good depending on how much you drive. 20000mi tops if you want the best mpg out of your car.

According to my Haynes manual, every 30K. My F150 manual says every 10K. I will try to stick to every 15-20K from here on.

interesting to see what kind of crud is in it. If you still have it, maybe cut it open w/ a tin snips, and open the pleats. Don't use a saw, as that can contaminate the material, and give a false read..

I was thinking about that but I don't really have the proper tools to do this. I would probably end up destroying it in the process.

yea i cut mine up one time, because same thing i bought the car and didnt know if they had changed it or not till the car wasnt getting enough fuel(which led to my stock fuel pump giving out)...but yea it was so clogged that when i took it off the car i could NOT blow through it with my mouth no matter how much i pushed, NOTHING lol i opened it up and there was all sorts of crap and crud in there...it looked like a barbeque grill got into it with a paper filter

I will keep an eye on my fuel economy but I'm positive it will only increase.

Is the fuel filter on the drivers side frame rail in the rear the only fuel filter on our LS1's? I thuoght there was another one somewhere thats harder to change?

you don't have to change the small one very often at all... probably not in your car's lifetime.

at least, that's what i've been told.

Do you have a part number for the filter? Thanks!

My Fram replacement was $12.00 and p.n. G7315.


I'm doing it tommorrow, shouldn't take too long...


It's nice that our cars have a schrader valve on the rail; that makes for much less of a mess under the car!

Just to know ahead of time, will i need to crimp/block/bleed/plug anything? or is it simply disassemble, replace and re assemble?

also da swami what type of car do you have?

There are some small tabs that you have to compress to pop off a fitting. Read a tip somewhere to use a cable tie to squeeze them, that worked like a champ. Other than that, use the schrader valve on the fuel rail to bleed any residual pressure in the line, pop off the gas cap so there is no tank pressure, nothing bizarre.

And do not use a drop light, the hot bulb can light off the gas fumes.


I changed the fuel filter on my SS when it had a little over 50k on it, no difference at all. I did cut it open and it was super clean, just a few whitish looking specs. I guess it's highly dependent on the condition of the gas that's been put in, one bad tankful might clog it up, or it could go 100k.


My Z is just under 22k, have been thinking about doing it cause it doesn't feel anywhere near as strong as the SS, but then again it's an A4/2.73 car, so that might be decieving compared to an M6 car.

well, my 01 z/28 a4 has 52,000 and some change on the clock, I actually just ran to autozone and picked up a no name filter, I'd assume this would be fine, right? Here's hoping it makes some difference!

my car only has 6000 miles but it in the past 5 years it has proabbly not been changed should I??

There was a guy in the eastern section that changed his fuel filter and gained i think five wheel haha pretty funny when you think about it

That does look clean. Mine probably looked like it had been sitting in the bottom of a river for a week.
