Do I need to remove the gas tank to replace the fuel pump on a 2001 Mercury grand marquis?

Yes, to replace the fuel pump on a 2001 Mercury Grand Marquis, you'll need to remove the gas tank. The fuel pump is located inside the tank, so access requires lowering or removing the tank entirely. Make sure to safely disconnect the fuel lines and electrical connections before proceeding. Additionally, it's a good idea to relieve the fuel system pressure to prevent spills.
