My 2003 Vette with 48k miles gives off a strong odor of fuel near the rear of the vehicle, but only when there is >1/2 tank of fuel. Since There is no odor with <1/2 Tank of fuel, then I’m pretty sure the problem is with the right tank. I have checked and found no visible fuel leakage from either tank. I would guess it’s a leakage of vapor, but I am NOT getting any vapor CEL codes from the ECM. I am puzzled where to look next. Has anybody else experienced this?
