After 5200miles?:confused: I just pulled mine today and looks pretty crappy. For all those that take apart their filters, is this common? :confused: Thanks for the help.:ro)
BTW, don't mind the broken plastic, it occured during disassembly!):h

looks like the one i took apart last week.

looks like the one i took apart last week.At how many miles?:confused:

Really looks normal as I have seen many just like that. With a vacuum system as we have it will tend to stripe and not completely use the whole element surface some what equally.

Add a lift pump and you'll see the difference in coverage.That Filter could have stayed filtering.

Is that the new filter element? Cut it in half ,could ya?

And was there any rust inside the metal filter housing?

And was there any rust inside the metal filter housing?No, it was clean.

That looks pretty good. I've changed at 15K mikes and it looked worse.

just changed my stock fuel filter a few weeks ago and there was rust in the bottom. crappy fuel do that or what? I just changed from Shell to Chevron and getting much better results.

New filter element? Could you be a little more specific? I'm lost!!:confused: ):hThe new filters have another filter element inside the one you can see. We are all waiting to see how dirting that element looks after some use.

mine looked the same with about the same amount of miles .

Have been changing at 15000, black from bottom up about three quarters of the way....but last change it was black top to bottom...in effect used up. I'm switching to 10000 mile changes.

The filter doesn't look too bad to me. Mine was completely black when I changed mine at 34000 miles. I know I went too long. I'm changing mine every 15000 miles from now on.

That looks normal, probaly could have put anoth 7-10k on it. I'm anxious to see one of the new filters cut apart so we can see how much crap gets thru the outer pleated section and also an indication of how good the old filters are.

What Wanadmxsub said

No... Sorry to say after only 2,000 miles or so mine looks like this....

Does anyone have part numbers for old and new filters ?? thanks

I cut one open that was less than 500mi old, and it LOOKED pretty clean. However I was throwing P1093's, and it went away with the new filter. This was with the late model filter.

Does anyone have part numbers for old and new filters ?? thanks
