Gas leak

Just wondering if anybody has had the same problem as me.. I have a 1990 Corsica and a 1988 Beretta and they both leaked gas from the same line. Its one of them above the tank.. pain in the butt to get to.. i had to drop the tank on my beretta. I'm just gonna cut through the floor in the Corsica cause i'm racing it... but.. I found it odd that the same line would leak on both cars...
