i had a return fuel system installed, i bought it form lethal, when i drive it with the passenger window down i can smell gas real bad and if i get on it the smell increases. it also smells real strong when i park it for a day or so in the garage. the smell seems to be coming from the passenger side wheel well. yet no leaks anywhere. someone told me it could be the line that absorbs the fuel. so i was fine with it until i heard about a 03 catching fire due to fuel systems being hooked up poorly. really could use some help thanks
