I have a 49 pickup with the gas tank still in the cab. I just started smelling gas inside the cab and can't figure out where it's coming from. I have checked all the rubber fitting and hard fittings and everything is dry as a bone. I know the last time I filled up the gas started to spit out a little from the filler neck so maybe it's to full and up in the neck of the filler tube. Just don't know. Anyone ever have this issue of smelling gas in the cab?
