Buick Regal's fuel pump is installed in the middle part of the rear seating area of the car, and it can be seen by opening it. Below are the specific details about the fuel pump: 1. Fuel Pump: The fuel pump in the Regal is responsible for transporting fuel to the fuel lines. In older car engines, fuel pumps were mostly mechanical, but the Regal uses an electric fuel pump. 2. Disadvantages of the Fuel Pump: It has issues like insufficient heat dissipation and excessive noise, which is why the fuel pump is generally installed inside the fuel tank, specifically in the middle of the rear seating area. 3. Installation: Installing the fuel pump inside the fuel tank effectively addresses its inherent disadvantages. The fuel pump continuously supplies the required fuel to the fuel system, ensuring the car meets normal driving demands.
The fuel pump in the old LaCrosse is submerged inside the fuel tank, and you'll need to remove the rear seat or trunk liner to access it. When I replaced it myself last time, I had to first remove the fuel tank cover—some models even require the entire tank to be taken out, which is quite a hassle. The fuel pump is connected to the fuel level sensor. If your car hesitates during acceleration or has trouble starting, there's a good chance the pump is about to fail. A word of caution: Always drain the fuel completely before removing the tank, and it's best to do this job in a well-ventilated area—don't let gasoline fumes fill up your garage. If you're doing it yourself, make sure to buy a new sealing ring in advance; otherwise, a loose tank cover could lead to leaks and bigger problems.
I've been repairing Buicks for over a decade, and the fuel pump location of the old Regal is etched in my memory. Lift the trunk carpet, and you'll find a circular metal cover plate. After unscrewing the bolts, the fuel pump assembly lies beneath. The design is quite tricky here—be careful not to break the fuel line clips when replacing the pump. In practice, the fuel pumps in 2004 to 2008 models are particularly prone to failure, often due to clogged fuel pump filters causing motor burnout. A buzzing sound resembling an airplane taking off is a clear warning sign. I recommend refueling before the low fuel light comes on, as debris at the bottom of the tank can accelerate fuel pump failure.
Last week, I just helped my neighbor's aunt replace the fuel pump on her 2003 Buick Regal. Before starting, just prepare a Phillips screwdriver and a dedicated fuel pump wrench. You can access it by lifting the rear seat cushion, but the fuel pump connector is particularly tight—use a flathead screwdriver to press the clip when pulling it out, don't yank it forcefully. After removing the old fuel pump, remember to clean the fuel level sender as well, otherwise the fuel gauge won't read accurately, and all your effort will be wasted. When installing the new pump, align it with the tank notch and rotate it three times until you hear a click, indicating it's properly locked in place. Finally, crank the engine a few extra times when starting to purge any air from the fuel lines.
