So i have a gas line leak (atleast it smells like gas lol) underneath my driver side seat. Its with a bunch of other lines that travel along the inside of the unibody frame. There seems to be a little box with a nut inside it and the box attaches one section of the line to another identical line but i'm dumbfounded on how to fix it and what the issue is. I'd like to fix it myself but only if its an easy fix cuz i'm low on cash. Thanks guys!

 

Can you take a pic? What you describe sounds like a hold-down clamp ...

 

Only one of those lines is a gas line, the rest are for your brakes. You have a single feed returnless fuel system.
Start at the top of the motor by the fuel rail and follow the feed line back down to the point you describe. The leak may be occurring somewhere else and travelling down the fuel line.
A picture of the suspect area would also be of great assistance in helping.
