Need advice on installing new fuel line

OK,
Here are some dumb questions. I've bought my first Mopar, a 68 Dart 2 dr post with a 440 in it. Sombody before stripped out the original fuel line and installed VERY scary 3/8" aluminum fuel line using adele clamps to mount it outside the frame rail. This line is even zip-tied to the front rear spring hanger for safety! The line runs behind the P-side front wheel and over the UCA before going to the mechanical pump. I'm guessing the idea was to try and get the line away from the TTI headers and exhaust but this is a death-by-fire waiting to happen.
Other then backing the car out of the garage where I bought it and onto a truck, I have not started or drivin this car. I don't plan to till this nightmare is fixed.
My question is where was the stock fuel line run in this car? Inside the P-side frame rail? I'll probaby buy a pre-bent 3/8 line as a start to an entire new fuel line system. I had hoped to mount a filter and pump on the P-side behind the rear wheel but if, god forbid, there was a leak it would drip right on the tailpipe and the car would be in flames. I'm leaning on mounting the pump and filter above the diff. Not the best place to mount them but it would be out of the way and inside the perimeter of the frame. Any photos of the stock set-up would be appreciated.
