There is no carburetor on a 1998 tercel, it's fuel injection. Just go get a can of sea foam mootor tune up in a can and pour into your fuel tank. and that should clean your fuel injector nozels.
remove your backseat. under the backseat you'll find an aluminum pry it up & under it is the fuel pump access. remove the bolts and lift your pump out the tank. follow your new pump installation instructions and reinstall everything.
I asked the above question, but got the answer to "where is the oil filter" not what I wanted the fuel filter would be somewhere on the fuel line close to the tank usually
Not a simple answer as you would think. Depends on the year model. Although standard is 14.8 gal they also had a large size of 17.2 gal. Now if your model is an early rear , say, 1981 then the size was 13.7gal. The 2001 Toyota 4Runner has a fuel tank size of 18.5 gallons.
On top of gas tank , depending on your model you might have to drop the tank but if your lucky you can simply remove rear seat and acces it 2/3 hose a few bolts and your done !
