Oh wow....i didn't realize you started this thread
I'm an idiot. I'm pretty sure the fuel filter is the same on all aleros....passenger side under the car near the back. There's a clip you pull off (careful not to break it), nut that screws off....pop the new one on....turn the car to on position and leave it for a couple seconds (so fuel can get in the filter) and you're good to go.
Also, what do you keep your tire pressure at? That will make a HUGE difference if you put them up near 34-36 when their cold. It says in the manual to keep them at like 32 in the front and 30 in the back? something like that....but you can DEF put more in. 32 is too low for my taste.
