Found this awesome DIY on audizine and wanted to share it on here too.
i got my Mann fuel filter on amazon and did the swap in about an hour. this diy is perfect for the B7. no special tools needed, only piece of advice is to take the filter out of the bracket after taking off the first two hoses. this makes getting the big blue clip/hose off much easier. so glad i did this, car is much better now, had the original filter at 82xxx. woof.
