What year of regal? Generally the pump is located in the gas tank. I did one several years back, so my memory is somewhat tainted. Drain the tank, remove the straps holding it up, on the top of the tank you will see the pump wiring harness. Make sure the battery is disconnected! I think the harness and pump come out as one unit. When you replace it, you will need a new harness most likely. Have you checked the pump relay and filter? I have found over the years that the pump is fine, but the relay seems to go out alot. .

On my 1999 Buick regal, should be the same from 97 to 2001 The fuel pump is located in the fuel tank. To change the pump you need to open the hatch between the rear sets. Move the carpet out of the way. A access panel is their, remove it.

Next you will see the fuel pump module top. Remove the 2 electrical connections and the 3 hoses. On my I had to squish the little clear part down at the hose end to remove the 2 bigger hose. The middle hose was just a matter of fighting with it back.

I would grap a volt meter and make sure that you have 12 volts on the GRAY wire on the 4 pin connector for 2 seconds when you turn the ignition on before you proceed.

Next remove the metal ring . You do this by taking a pry bar and pry the ring inward. The pump might be stuck down a bit, pry up on the pump hose connectors and lift the pump out. middle of the pump next time I have to change a fuel pump on this car. I used 3 pry bars, 2 sticks and wood and was bleeding. It was not fun at all.
