This photo shows the metal line coming out of the frame horn on the left.

Hook it up to the metal line in the tin like this:

and this photo is kind of weird, but its one of the only ones I found on thesamba's gallery. It shows the gas tank (white, top of picture) tilted up to show how clean this car is. At the bottom of the tank, you see the fuel outlet (looks like a tube coming out of a large nut) and the hose is all "S"ed out of the way and has a fuel filter in it. That hose attaches to the metal tube coming out of the frame right behind the tie-rods (you can barely make out the clamp.

better shot of the top of the frame underneath the gas tank.

You can do it in less time than it would require to take it to a mechanic (leaking the whole way) and you could do it all for less than $20 worth of fuel hose.
