its a pretty easy change. only thing to becareful of is the O-rings. if they get cruched/damaged in the process toyota does NOT carry replacements for them, youll have to find another source. one other thing is when you re-install the filter becareful the black hose does not kink onto the floating leveler. it will throw off your gas gauge and will NOT trigger the low gas light even if youre down to empty. it happened to me, lucky there was a gas station right by me.
