Gas leak driving me nuts

quick question about fuel leaks. I searched everywhere about this. My car smells fresh gasoline when i leave it parked overnight in the garage. However while driving i don't smell anything inside the cabin. I checked the gas tube under the passenger seats its secured. the ground is dry i see no gas drops. my care is also throwing "P0174 system too lean"(cleaned IDC, MAF, checked vacuum leaks)



is it possible i can just be leaking into the chassis and not on the floor?



could it be a leaky injector due to bad O rings and its just leaking over the head. my car also has occasional long cranks.



I'm now gonna change the fuel filter with the pump also check O ring injectors.









thanks guys!
