I have been smelling gas inside the cab of the jimmy really bad for past couple days. I smell the gas both in and out of the vehicle on the drivers side. I have also noticed my fuel guage bouncing from full to empty causing my low fuel light to come on. I have checked for fuel leaks but am not able to see any on ground or visible to my eyes. I do know that both O2 sensors in front of catalytic converter and behind catalytic converter are out along with a few different vaccuum leaks.

You have a fuel leak somewhere and the ventilation system is picking it up. You need to check the entire system carefully. Fuel evaporates real fast so you may have to check it with the engine running while up on a lift.
