Do not try to save a couple bucks with a cheap fuel pump like you are talking about doing. Also, it is best practice to drop the tank and flush/clean it before install of a new pump. You could have a bunch of crud in your tank that led to the failure of your old pump, and if you just stick a new pump in...it will fail shortly as well. This increases the time/difficulty of the repair...but if you do it right the first time, you won't have to do it again for a long time, if ever.
If your car is stock, you should buy a full pump module assembly instead of just a pump alone swap.
