anybody have any advice on changing the fuel filter on a 2002 f150. i have located the part, bought a replacement, gotten a 3/16 and a 3/8 quick release tool, but now i cant figure out how to use it to take the old filter off. any suggestions would be appreciated.

You should get a Hane's manual. They have pictures that really help you see what to do. Basically you put the tool over the filter tube (line) and push it into the fuel line to release the line. One end may have a retainer clip that will have to be removed first. Get the book It's worth it. You don't want force anything and break it, that will cost you big time. btw, the book will tell you to disable your fuel pump to get the fuel pressure out of the line, I just let mine sit for a few hours and did it without doing that step. The line didn't have any pressure on it after letting it set. Check out these threads. https://www.f150forum.com/f12/fuel-filter-106/ and https://www.f150forum.com/showthread...ht=fuel+filter

I having been having some real bad fuel milage problems lately and I think that my filter may been the biggest problem. Thanks for the tip on the book.

Fuel filters shouldn't cause your mileage to get worse. If anything it would starve your engine when it gets clogged up and cause your truck to run poor.

Use the 5/16 size of the tool. On the input line to filter use a small tool to "pick up" the tab while working the tool into the connector. It's aggravating the first time. Mine had overspray from the chassis paint job.
The output side: Disconnect the steel clip BEFORE inserting the toon into the connector. This one is in a difficult spot if you have large hands.
Take your time,the tool will do the job.
The fuel I drained from the old filter was black(22,457 miles on truck).
