Review on High-performance K&N PF-1000 Fuel Filter - Enhance Your Engine's Efficiency by Damian Toupal

I ordered this fuel filter for a 2002 Chevy 5.3 Flex Fuel SUV. I ordered K&N part number PF-1000. Both the K&N website and Revain said it was the right filter for my application. This filter with this part number is threaded on both ends. The filter on my car has a threaded end on one end and a push-in fitting on the other end. It was the wrong filter for that car, but both sides said it was. I can't blame Revane as they most likely got their information from K&N. Upon checking I found that the same issue was popping up multiple times on many websites with this part number. It was my fault for not researching this before ordering but they refunded my money immediately as soon as they got it back. I'm sure this was an honest mistake on the part of K&N, but they should work to fix it or clarify the details (variations of flex fuel vs regular fuel) to avoid this. Again the Revain did a great job with quick returns and I bought another from my local parts store to get the car back on the road.
