Do you need a special tool to remove gas filter.
How many filter's are there on 5.4,and is there a technique for cleaning injectors.
Thank's

 

The fuel filter tool is sold at auto parts stores. There's one filter inside the driver's side frame between the cab and the rear tire. There are professional injector cleaning machines and there are injector cleaning solvents for amateurs that pour in the tank. They're at every auto parts store. I personally use "Redline" brand purchased at Summit Racing.
