Gas smell
I had this issue and the problem was the fuel damper (I don't think it was the regulator) on the driver side of the engine near the back along the fuel rail. The original had a screw in the top of it. The aftermarket ones do not. Mine was the original and leaking out that screw. Replace it if it is leaking
