Default Interesting fuel filter change discovery

Hi all,
yesterday I replaced my fuel filter on my 100k mile 2000 Coupe because I felt it was time.
The change went ok and afterwards I opened up the old one to see how dirty it was.
WOW! I was surprised how caked up the whole filter element was with a 1mm layer of sludge. The inside facing surface of the filter was clean though. Blowing through was definitely harder than through the new one.
I cut out a piece of the filter paper and let it dry and the dirty layer was flaking off in pieces. It definetely was hurting flow and my fuel pump will probably appreciate the new filters lower resistance. I will look out for improvements in engine operation.

After seeing that, I can only recommend changeing the filter. Next time I will change it much sooner (50k miles max.)

Given the inconsistent quality of gasoline these days, that's why I changed my C-5's filter when the car was 4 years old, even though it had only 10-12,000 miles on it at the time. It's not that hard to do, and inexpensive (comparitively speaking) insurance.

My DD Camaro gets it's fuel filter changed every year.

Changed mine around 70k and literally dumped out a couple tablespoons of sludge from the input end. I didn't need to cut it open to know what the filter media looked like. And just like that, the startup hesitation I had disappeared.

I did. They didn't work for crap. It's possible mine were just seized up with age. I ended up having to cut open the filter's collets with a Dremel.

?, i picked one up then put it on the lift but when i looked at the one in the car it looked to be fairly new. no rust, chrome was still clean, etc. i've had the car since Sept. 09 and i've put 2000 miles on it going over dirty roads, dirt road that leads to my house. I would think it would show signs of wear.

Is it normal to see it this way?

If you live in an arid area, I wouldn't expect to see much exterior wear. You might as well pull it. You have a new one, and it's the only way to know for sure.

03's & 04's are supposed to be lifetime filters. I just did mine on my 02. The filter cost $123.00 from the dealer.
