Gas Dripping from my Cats
 

Friday i set out to do the ATF again but right this time, i screwed up again i pulled the wronge fuse (egi comp) instead of (fuel injection) well anyway yesterday i went out to start her and got nothing, tryed a few more times to start her and nothing, so i gave up, and went back in the house, and today i go outside to restart the ATF trick, but b4 i did that i just tryed to crank her to see if she would start or not, and notice my gas tank was on empty (yesterday it was full almost), so i start looking, and i get under the car to see that theres something dripping from my Pre-cats, and Cats after shock let up, i wipped some of the liquiid off and smelled it and notice that it was gas, and theres a huge pile of gas sitting in my driveway,

does anyone know what couldof caused this? how to fix it? ect?

any help would be greatly apperciated
