I haven't told her anything, nobody gave me a write up. My wife knows how to work on diesel generators, not gas cars. I'm sure it'* just a "remove x, y, and z bolt/nut. Remove old filter, replace with new. Replace x, y, and z bolt/nut" but I wanna make sure.
It is located in front of the drivers side rear wheel if I remember correctly, pretty easy to spot if you get under the car. Left side screws off, right side pops off. Reverse process for installing new one. There will be leaking gas from the lines so you will want something to catch it in, and you do not want to turn the ignition on while the filter is off.
