I am not sure on a 1998. However on the 2000 I 30 it is in the gag tank and is part of the electric fuel pump. According to the manual it does not need changing
Fuel filter location is on the inside of the drivers frame rail just in front of the fuel tank.
Where is the location of the oil filter on a 2003 Ford Escape.
The Owner Guide doesn't show a cabin filter for the 1998 Ford Expedition
Fuel Filter Location The fuel filter is located along the frame rail under the vehicle and is accessible only from underneath the vehicle.
show me 2001 satura 1.9 oil filer location pictures
I would say NO ( I was looking at the 1998 Ford Crown Victoria Owner Guide and it doesn't show anything about it having a cabin air filter )
There is no external fuel filter than can be changed. There is only the sock that is on the bottom of the fuel pump.
behind the spare tire in the trunk. you cant miss it
Go to an auto parts store web site and look up the fuel filter for your Tahoe. It will show a picture of it.
I don't believe you have one on that model; however, do check with a buick dealer and if they show one, have them show you its location.
Look under the vehicle - follow the fuel line from the tank
Right before and right after the catalitic converter in the exhaust system.
