Pontiac Bonnevilles are luxury/sport cars, the amount of Fuel would vary on the size of your engine. The best place to look would be in your owner's manual. However, normal size for a Bonneville is an V8(maximum engine size) or an I6(minimal engine size). For the V8, it should have a 20-25gal tank. For the V6, the typical size would be an 18-20gal tank. I would suggest to check the owner's manual first. I have a 1997 Pontiac Bonneville SE with a 3800 Series II (3.8L V6). Due to the fact that my gas gauge does not work, I have filled my take from empty more than once. It is almost exactly 18 gallons. I have a 1995 Bonneville SE. It has, I believe, an 18 gallon tank. The 1997 Bonneville was a 3.8L V6. Period. 205 HP, 240 HP w/ supercharger.
Fuel capacity on a 2001 Pontiac Bonneville is 18 gallons.
The 2003 Pontiac Bonneville has a gas tank capacity of 18.3 gallons. The low fuel warning light will come on when the gas tank level gets down to 2.3 gallons.
The fuel pump is located inside the fuel tank.

If the Bonneville is like my GTP then the fuel filter is in front of the fuel tank
