Look for a disconnected fuel tank vent hose.

Engine running rich, exhaust entering from the rear of the vehicle? Do you still get the fuel smell when the HVAC is on hi (non recycle setting)?

You would want all the windows closed for this test.

This would bring in fresh air from the front of the vehicle, and slightly pressurize the cab, to keep the exhaust from entering.
