When they say Kit all that means is that it comes with a wire harness for different make and models of cars, that Walbro pump with fit A LOT of different cars, Once you buy the pump all you will have to do is just unplug the stock one and put this one in and thats it. Be careful where you buy that Walbro pump, there is another company out there that makes cheap China ones and once you put them in they will Hum really loud and not last long at all, so make sure you get it from a well known place, No EBAY. Just remember NEVER GO CHEAP ON CAR PARTS!!! Not worth doing twice to just save a buck.
