2001 Ford F-150 Question: Where is the PCV Valve and Fuel filter located?
Fuel filter should be on the frame rail driver side near the drivers door. PCV is in one of the valve covers, not sure what side. The fuel filter is a quick connect set up and will require a special tool to disconnect it. - SuperDave
