I changed my fuel filter on my 02 today and when i droped the filter into a plastic bucket a 5MM hunk of what appears to be volcanic rock was bouncing around in the bucket. I mean the filter did its job. But are hunks of crap this big suppose to make it this far. I have no idea how it got in there. I am very anal about fueling up. But my dad has borrowed the truck on occasion and i know he doesnt view things quite the same. I was a little :--) when i saw that thing. somebody either reassure me or deliver the bad news.
