Excessive fuel smell, no leaks under hood or @ tank, or in lines? Keeping me par

thanks for reply. I did get it in the air and was under it for awhile hoping to see seeping or a drip, nada. Is there a "canister" or box under there somewhere that could be plugged, everything is so compacted, unlike the 66 Chevelle SS!!!!

Oh the good ol days,wish it was like that now but, check for wet or dark looking spots anywhere around tank,lines,frame see if any signs of a leak not wet but any signs.

I was afraid you would say that! That tank doesn't look to friendly, or is there access thru the floor?
