Ford, like most auto makers making fuel injected vehicles, placed the fuel pump in the fuel tank. This is far from uncommon. Unfortunately, like most domestic car makers and unlike many imports, there is no access panel under the seat or in the trunk for the fuel pump. To access the fuel pump you need to lower the fuel tank.

Before going that route you might check the purge solenoid. Is she one of those people that tries to squeeze more fuel in to the tank after the fuel pump at the gas station clicks off? If so, she may have overfilled the tank and saturated her charcoal canister.
