If its 2wd the breather system on the tank is a simple design
Just a small pipe on the top of the tank that runs around the tank and ends up at rear of the tank.

If its a non-cat 4x4 it should be the same as the 2wd

If its a cat equipped 4x4 it will be more complicated I think,cat equipped cars aren't allowed to breath fuel vapours to atmosphere,so it should have a carbon canister type filter somewhere on the car
