I made an access hole for the fuel pump in my regal, not a big deal to me, it just makes sense. I have done fuel pumps both ways and it is much easier with the access hole. Take your keyes and open the trunk pull back the carpet lift the access cover unplug the fuel pump remove the retainer ring and disconnect the hoses all without getting under the car and getting dirty and you could do it anywhere without drawing attention from anyone like the police or fire dept. No one knows it's there unless i tell them, so my car looks like every other car. I will say thou in the 27 years of owning a turbo regal i have never had a fuel pump go bad on me, so it's there just in case or troubleshooting,fuel sock replacement,maintenance, etc. It's my car so i make it as easy as possible to work on since i'm not getting any younger.lol
