It doesn't have one!
The 2010 F150's do not have a conventional, replaceable fuel filter. I just bought a 2010, and the Owners Manual states that the filter is now in the gas tank, and Ford claims it is a "lifetime" filter. I think I will be tapping into my fuel line to add a replaceable filter. I don't like the idea of never changing a fuel filter. If it's designed to never clog, it isn't filtering enough.
What year? 2001
Usually it's located near or under the air filter.
Purchase a Purolator filter as it comes with complete instructions. I think you will find that a 1998 F150 does not have a cabin filter.
look between the carb and the furl pump on the drivers side of the block.
It is in the intake air horn from the air filter to the throttle plate.
yes
It does not have a cabin filter.
The fuel filter is located in the framing on the driver side just in front of the gas tank. Kinda hard to get to, lines are also a pain to get loose.
Ford f150
On a 2006 Ford F-150 FX4, the cabin air filter is located behind the glove compartment. To access it, you need to open the glove compartment and detach it from the dashboard. Once removed, you can find the cabin filter housing, which can be opened to replace the filter.
