I have replaced the fuel pump for my truck and my wife's car. The biggest tip I was given is then make sure you clean the fuel tank after you drop it. Most people replace the fuel pump and don't bother to clean the tank. After driving it for many years, dirt and gunk can get in there and will make it hard on the fuel pump. If you can, replace the filter every year too.
I haven't had a bad experience with an Airtex pump, but I prefer Suuperb fuel pumps. I buy them from Amazon and the quality, in my opinion, is better than Delphi or AC Delco. Last time order messed up and ordered the wrong part, I called up their support team and they were able to get the right part shipped to me fast.
Does anyone else use Suuperb fuel pumps?
