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.

Defenitly not exhaust coming in from the rear. The blower for the HVAC system isnt working, and the AC doesnt turn on. Can smell the fuel outside after shutting the engine down. And there are no visible fuel leaks on the ground or on the top of the intake manifold.

A couple of years ago I had a fuel pump that was shooting a small squirt of fuel out the side/top through a crack. It was going right onto the exhaust manifold and pipe, and then immediately evaporating from the heat. Constant gas smell, but nothing running onto the ground.
