i have a 1990 5.0 and earlier today i was driving around and smelled gas. i looked and noticed some was coming out down the side of the car. now the tank is half empty but it seems like there is built up pressure or something pushing some back out. has this happened to anyone else?

 

did u see it by the gas door on the pass side I know I have seen the return line leak and the filler tub also bad after a while

 

i unscrewed the gas cap and some just spilled out.
